Drones are coming soon to a farm near you
Remote Sensing

Professor and students stand with drone.

Jan van Aardt, back, professor of imaging science, and his graduate students use imaging systems on drones to develop precision agriculture practices. Left to right are: Ethan Hughes, MS student; Ali Rouzbeh-Kargar, Ph.D. student; Ronnie Izzo, MS student; and Amirhossein Hassanzadeh, Ph.D. student.

Drones are adding a new level of precision to agriculture, giving farmers digital tools for cultivating better and more profitable crops.

“The machinery that large farms use—big combines and sprayers—they can take input from GPS and it automates the application process of fertilizer, for example,” said Carl Salvaggio, RIT professor of imaging science. “This technology can also spatially tell you where to harvest to get the best crop product.”

Salvaggio and Professor Jan van Aardt are developing imaging systems at RIT that could make drones commonplace on farms in western and central New York, enhancing the Finger Lakes region’s focus as a food hub, while creating the supporting technology and software companies.

Salvaggio, who leads RIT’s signature research program in unmanned aerial systems (UAS) imaging, offers some ideas on how drones can help farmers.

For instance, accurate measurements of soil nutrients and moisture level, disease risk, and plant maturity could take the guess work out of predicting harvesting and processing schedules. Information captured by specialized imaging technology could also reduce the need for chemical controls, by indicating where, when, and how much to apply.

RIT’s remote sensing expertise could also establish technical standards that ensure the scientific integrity of the fledgling industry.

Salvaggio, who primarily conducts research for the defense industry, is taking the lead in atmospheric compensation, calibration of imagery, and radiometric processing to ensure continuity in imagery collected over time.

It’s a point of pride for the RIT researcher; if the imagery isn’t adjusted for atmospheric differences between scenes, dramatic changes in illumination between a sunny morning and an overcast afternoon will skew the data and lead to misinformed decisions at the farm level.

“A lot of people are flying without calibrating their data, and they’re providing data that, to them, looks right,” Salvaggio said. “There is so much promise in these systems, but if you lose the faith of the farmer, you’re never going to get it back, and that could make an industry flourish or totally bankrupt it.”

A regional collaboration of strategic partners, called the FARMS (Fostering Agricultural ReMote Sensing) Alliance, is developing both the unmanned aerial systems technology and the best practices for using it.

Van Aardt is leading this National Science Foundation-funded project focused on remote-sensing applications in snap bean production.

The crop is economically important to New York as one of the biggest producers of processed and fresh market snap beans, following Wisconsin and Florida. The U.S. Department of Agriculture, in 2015, ranked snap beans as the fifth largest vegetable crop, in terms of acreage, with a $416 million market value.

The availability of a commercialized imaging product for managing white mold, predicting crop ripeness, and estimating the snap bean yield could have a big impact on farmers.

That is welcome news to Jeff Johnson, agricultural manager at the Seneca Foods Corp. location in Geneva, N.Y., who has been talking to van Aardt for years about the need for a better way of managing crops with imaging technology. Johnson is responsible for growing 10,000 acres of snap beans for one of the nation’s largest vegetable processors and relies on crop scouts to monitor the ripening pods and look for signs of white mold.

“When we send people out to the field, they are walking a path,” Johnson said. “We send a drone over the field, it can see the whole field. In theory, we can have a better picture of that whole field than our person does by just walking through it, and labor is becoming more expensive and harder to find.”

The crops are staggered because the processing plant can handle only so many tons per day, and the tight operating schedule isn’t negotiable.

“In our world, there’s a 24- to 72-hour window when the beans are ripe,” Johnson said. “It’s critical from our planning standpoint knowing when those fields will be ready to harvest.”

The challenge of predicting plant maturity is pushing the limits of remote sensing. Van Aardt is combining hyper­spectral imaging to capture light signatures and LiDAR (light detection and ranging) sensors to build a spatial, three-dimensional or topographic picture. “We’re trying to fly a drone, look at a snap bean plant—not even the pods—and see if there is a signal in the plant that tells us the pods are mature or ripe,” he said.

And when it comes to white mold, van Aardt and imaging science MS student Ethan Hughes are identifying the spectral and structural indicators that influence pesticide timing and disease risk. “We want to see—even before the mold occurs—if we can predict where disease incidence will be the highest, so farmers can spray only in those areas,” van Aardt said.

“Remote sensing techniques in agriculture hold the promise of standardizing crop assessments with a scientific accuracy not possible from manual observations,” said Sarah Pethybridge, assistant professor of plant pathology at Cornell University.

A white-mold expert, Pethybridge, along with Julie Kikkert at Cornell’s Cooperative Extension, are already developing risk models for snap beans with Salvaggio and van Aardt for an ongoing U.S. Department of Agriculture study. Pethybridge’s project inspired van Aardt to form the FARMS Alliance.

“From the exploratory research done with RIT, we have good spectral signatures to detect flowers, which is an important step in identifying optimal timing of pesticides for white-mold control,” Pethybridge said.

The goal for Salvaggio and van Aardt is to get the information products into the farmers’ hands.

“We use expensive sensors with hundreds of spectral or color channels, but we actually only want to identify five or fewer channels that are useful for specific applications,” van Aardt said. “Then we can transition those five channels into a more affordable sensor that a farmer or a service provider could use operationally.”

Other agricultural projects

Drone data collection

RIT is leading the FARMS (Fostering Agricultural ReMote Sensing) Alliance to develop and commercialize drone data collection and analytics for the agricultural industry. The project is supported with a $750,000 National Science Foundation grant and brings together strategic partners in the Finger Lakes region. The core research and technology transfer team includes RIT’s Chester F. Carlson Center for Imaging Science, Saunders College of Business, Venture Creations technology business incubator, Cornell University and Cooperative Extension; the FARMS Advisory Council and Commercial Partners consists of Harris Corp., Agrinetix LLC, Headwall Photonics, Seneca Foods, Love Beets, and Farm Fresh LLC.

Risk models for white mold

RIT researchers are collaborating on two agricultural studies led by Cornell University—one focused on developing risk models for white mold on snap beans for the U.S. Department of Agriculture’s Critical Agriculture Research and Extension Program, and the other to evaluate the table beet production for improved profit and sustainability for Love Beets.

Solving world hunger

Improved safety of unmanned aerial systems (UAS) and drone control software has paved the way for the Federal Aviation Administration to relax restrictions on commercial drone flight. The integration of drones into the national airspace will position the United States to take a stronger role in the global $32.4 billion UAS agriculture market, according to an independent analysis from PrecisionHawk Inc. The technology and data analytics provider collaborates with RIT researchers and has provided the use of its drone platforms.

Agricultural drone imaging has emerged as the dominant focus of RIT’s unmanned aerial systems imaging program, a signature research area. Digital agriculture techniques could help feed the world’s growing population, which the United Nations predicts, by 2050, will reach 9.8 billion and will demand a 70-percent increase in food production from 2006.

Solving global problems with precision agriculture resonates with students in the Chester F. Carlson Center for Imaging Science, said Carl Salvaggio, who leads the signature research initiative. The potential benefits in the agriculture drone industry have sparked interest among students who see a way to make a humanitarian difference.

“We have a lot of students who want to contribute to solving this global food production need,” he said. “It’s exciting that we can attract a new kind of student to imaging science.”

Researchers from RIT and Seneca Park Zoo recently journeyed to the Centre ValBio field station in Ranomafana National Park on a trip that laid the groundwork for creating accurate 3D models of the exotic Madagascar wildlife and habitat.

Researchers from Rochester Institute of Technology and Seneca Park Zoo are developing a virtual reality gaming environment that will let zoogoers experience a Madagascar rainforest ecosystem. They recently journeyed to the Centre ValBio field station in Ranomafana National Park on a trip that laid the groundwork for creating accurate 3D models of the exotic Madagascar wildlife and habitat.

RIT Professor Anthony Vodacek and Seneca Park Zoo Society Director of Programming and Conservation Action Tom Snyder used remote sensing equipment to examine animals including comet moths, scorpions, katydids and other large insects. The goal is to create the virtual reality gaming environment in the next one to two years.

This will be the second gaming experience RIT and Seneca Park Zoo have created for zoogoers. The zoo is currently beta testing a game that simulates the Genesee River ecosystem. Visitors can play as an otter, a farmer, a homeowner or a scientist to learn about how their actions impact the environment. Snyder said Seneca Park Zoo Society’s partnership with RIT, which was formalized in 2017, has opened his eyes to new approaches to preserving the environment.

During their trip to Madagascar, RIT Professor Anthony Vodacek, second from right, and Seneca Park Zoo Society Director of Programming and Conservation Action Tom Snyder, left, also visited with researchers from the University of Antananarivo.

“There’s a really cool overlap between technology and conservation,” he said. “You don’t necessarily need to be a conservationist or a biologist to do these types of projects. There’s an interesting and exciting future for remote sensing and many other types of technology in conservation.”

Vodacek worked with Tim Bauch, a senior lab engineer in the Chester F. Carlson Center for Imaging Science, and Morgan Webb, a first-year motion picture science student from Greenwood, Mo., to develop a prototype for a multi-view imaging system to capture the 3D models of the Madagascar wildlife. Vodacek also used a ground-based LIDAR system created by Professor Jan van Aardt to scan the structure of the forest and field microphones to passively record sound for the visualization aspects of the gaming environment. Now that he’s had an opportunity to test the equipment in the field, Vodacek can refine the process and said he sees larger applications for remote sensing insects.

“It would be huge for biodiversity and the agricultural applications of that are enormous,” said Vodacek. “But it’s a very difficult thing to be able to do, and people don’t talk about remote sensing of insects. I saw this as a preliminary step at expanding the ways we can look and listen for insects. The best process would involve multiple methods all at once—audio, imaging in the visible, infrared, ultraviolet fields.”

Vodacek said his trip, which received funding from the RIT Global Office and College of Science Dean Sophia Maggelakis, opened up the possibility for RIT students to study abroad at Ranomafana National Park in the future. He called Madagascar an ideal spot for research because of the abundance of endemic species that can only be found on the island.

While Vodacek prototyped one system to create 3D models of insects, freshmen in RIT’s imaging science program are also creating similar systems for their project-based Innovative Freshmen Experience class. The students will display their findings at the Imagine RIT: Creativity and Innovation Festival on April 27.

Imaging a future for the past – uncovering lost text from manuscripts
Cultural Artifact and Document Imaging

(Photo by Grgo Jelavic and Vedran Levi)

Mar. 21, 2019

RIT Croatia Dubrovnik campus, in cooperation with Dubrovnik libraries, had the honor of hosting and organizing a series of lectures, a workshop and a round table discussion on the topic "Imaging a future for the past – uncovering lost text from manuscripts” that took place from March 18-20, 2019.

This first lecture was held on March 18 at the Dubrovnik campus and it was open to RIT Croatia students, as well as to students from Restauration program at the University of Dubrovnik. The audience was first greeted by Dr. David Messinger, professor at the Xerox Chair in Imaging Science and Director of the Chester F. Carlson Center for Imaging Science at RIT, who introduced the topic, followed by Ms. Tania Kleynhans, RIT’s PhD student on hyperspectral image analysis of illuminated manuscripts and paintings and Dr. Roger Easton, professor at RIT’s Chester F. Carlson Center for Imaging Science.

The overall idea of the lecture was to introduce Cultural Heritage Imaging as a growing field of research into the use of novel imaging techniques to study historical objects of known or unknown significance.  Of particular interest are imaging techniques that go beyond the capabilities of the human visual system to discover new information about artifacts, either through the enhancement of faded or otherwise unreadable text, or through techniques that study the materials used in the creation and modification of the objects (i.e., pigments, substrates, tools, etc.).  The audience could see a high level overview of multispectral imaging and how it is used to "see through” faded, damaged or palimpsested texts. Examples of discoveries made through spectral imaging were also shown and discussed, which was particularly interesting, being that examples included new discoveries within the famous Archimedes Palimpsest at the Walters Art Museum in Baltimore, the World Map by Henricus Martellus Germanus that is located at Yale University and many other. The lecture on the same topic was repeated at the Dubrovnik Public Library the same day and it was open to general public.

On March 19, there was a workshop that took place at the Dubrovnik Scientific Library and the goal of the historical spectral imaging workshop was to familiarize librarians, curators and scholars with the capabilities (and shortcomings) of spectral imaging. The workshop was also delivered by. Dr Messinger, Dr. Easton and Ms. Kleynhans, and it consisted of short presentations about successful recovery of texts, the basics of spectral imaging, and a high-level overview of how these imaging systems works. Moreover, the RIT team took the opportunity to image a handful of objects from the Scientific library such as parchment fragments, possible palimpsested material and faded text in order to explain and demonstrate the imaging process. This was followed by a discussion and demonstration of how to process the collected images in order to uncover the lost text.

This fascinating series of events was concluded by a round table discussion that took place on March 20 at the Dubrovnik Scientific Library. RIT representatives were joined by local specialists in the field of conservation and Restoration to discuss the outcomes of mentioned lectures and workshops as well as possible future cooperation.

"The entire visit could be seen as a gold-mining expedition. And I believe that we stroke gold! Dubrovnik has a lot of hidden treasures waiting to be discovered. Through a solid support from RIT, such Croatian establishments as the Libraries of Dubrovnik and the State archives in Dubrovnik, could have the means to increase their significance as repositories of cultural and heritage assets with the hope of becoming more attractive for scholars and researchers from all over Europe” concluded Dr. Francis Brassard, professor at RIT Croatia and coordinator of the event.

RIT researchers developing ways to use hyperspectral data for vehicle and pedestrian tracking
Remote Sensing

CIS plays a central role in new research project sponsored by the Air Force Office of Scientific Research

Mar. 5, 2019

Three researcher watch hyperspectral camera on roof.

The Air Force Office of Scientific Research (AFOSR) funded a Rochester Institute of Technology project to utilize hyperspectral video imaging systems for vehicle and pedestrian tracking. The project will use the hyperspectral video system shown above, which was developed by Associate Professor and Frederick and Anna B. Wiedman Chair Charles Bachmann, left.

A classic scenario plays out in action films ranging from Baby Driver to The Italian Job: criminals evade aerial pursuit from the authorities by seamlessly blending in with other vehicles and their surroundings. The Air Force Office of Scientific Research (AFOSR) has Rochester Institute of Technology researchers utilizing hyperspectral video imaging systems that make sure it does not happen in real life.

While the human eye is limited to seeing light in three bands—perceived as red, green and blue—hyperspectral imaging detects bands across the electromagnetic spectrum far beyond what the eye can detect. This high-resolution color information can help us better identify individual objects from afar. The AFOSR awarded a team of researchers led by principal investigator Matthew Hoffman, an associate professor and director of the applied and computational mathematics MS program, a nearly $600,000 grant to explore if hyperspectral imaging systems can do a better job at tracking vehicles and pedestrians than current methods.

“It is very challenging to track vehicles from an aerial platform through cluttered environments because you cannot really see a vehicle’s shape as well, and a lot of machine learning computer algorithms are based on shapes,” said Hoffman. “Buildings, trees, other cars, and a lot of things can potentially confuse the system. As hyperspectral video technology has improved, we believe we can use color information to more persistently track targets.”

The project will require a multidisciplinary approach and Hoffman will work closely with researchers from RIT’s Chester F. Carlson Center for Imaging Science. Co-PIs include Professor Anthony Vodacek, Distinguished Researcher Donald McKeown and Assistant Professor Christopher Kanan. The project will use a hyperspectral video system developed by Associate Professor and Frederick and Anna B. Wiedman Chair Charles Bachmann. Senior Research Scientist Adam Goodenough and several Ph.D. students will also collaborate on the project.

The challenge with using hyperspectral imaging is that it produces massive amounts of data that can’t all be processed at once, so Hoffman and his team are also tasked with creating a process to efficiently use the information on demand. The team will use the Digital Image and Remote Sensing Image Generation model developed by RIT’s Digital and Remote Sensing Laboratory to develop a new dynamic, online scene building capability that helps re-track targets after they have passed by obstacles. Hoffman said he is excited by the prospect of creating such a unique product.

“This would be a dataset that just doesn’t exist today, so it would be a really novel solution,” he said.

The three-year project got officially underway in December. The goal this year is to develop the system’s infrastructure and the team hopes to mount the system on a plane at the start of year two to begin testing.

Catherine Carlson, longtime area philanthropist and community booster has died

Sep. 27, 2018

A woman who is known for her philanthropic activities in the Rochester area as well as her connection to the founder of Xerox has died.

Catherine Breslin Carlson was 91. Her friends say she died peacefully on Thursday morning.

cheap nike free run 5.0

Catherine Carlson was originally from Milton, Massachusetts, and moved to Rochester in 1969. She graduated from Boston University with a degree in philosophy, and after graduation embarked on a business career, including assisting the head of Leahy Clinic, working on staff with boat builder George O'Day, traveling for Connecticut General Insurance Company, and serving as registrar and development officer at Tufts University School of Dental Medicine.

While in Boston, Catherine met Rochester inventor Chester Carlson and his wife Dorris, and when traveling to Rochester on business, she often stayed at the Carlson home.

Chester Carlson developed the Xerographic process, which eventually led to the founding of the Xerox Corporation.

After Chester Carlson died in 1968, Dorris invited Catherine to assist her and continue Dorris and Chester's philanthropic work and support of spiritual interests. When Dorris died in 1998, Catherine became  Chair of the Chester and Dorris Carlson Charitable Trust.

That trust was administered through the Rochester Community Foundation. Its President and CEO, Jennifer Leonard says Catherine Carlson had a strong need to help people throughout the city.

“Going out beyond the club life, let’s say, of a lot of other people from her social strata and recognizing the needs of the poor and the hungry and of struggling women and families."

Catherine Carlson also has given many talks at scientific conferences about Chester Carlson and his achievements.

She served the community in a variety of ways, including founding the first lay Board plotting the future of the merged Nazareth Schools, Nazareth Academy and Nazareth Hall.

Catherine Carlson served on a number of boards, including the Rochester Area Community Foundation, the Rochester Philharmonic Orchestra, Greater Rochester Women’s Fund and the Reynolds Library benefiting the Rochester Public Library.

Libraries were a particular focus of her philanthropic activities. The University of Rochester campus is home to the Carlson Library, which houses most of the university’s scientific collections.

Catherine Carlson also funded the Patent and Trademark Resource Center to assist inventors in patent procedure based on Chester's early experiences as a patent attorney and provided scholarships to RIT's Carlson Imaging Center, Nazareth Academy, and Nazareth Elementary School.

Mary Ann Mavrinac is the Dean of the University of Rochester Libraries, which includes the Carlson Science and Engineering Library. A number of archival materials from Chester Carlson are housed there, but Mavrinac says Catherine Carlson didn’t just reminisce about past accomplishments.

"She was always thinking about the world in which we live. She had a great concern about the community and poverty and poverty in certain segments of the community," Mavrinac said.

Sister Beth LeValley of the Sisters of St. Joseph in Rochester  was a close friend of Catherine Carlson for a number of years. She remembers Carlson's interest in education and reading. "She would go and read to the students and all that, and then the migrants, I still remember going out to the Brockport migrant school which was at the former Nativity School, and, oh my gosh, reading to the kids and the kids had their shields,  and she was very good with children like that," Sister LeValley told WXXI News. 

Mayor Lovely Warren issued this statement:

"I am deeply saddened to hear of the passing of Catherine Breslin Carlson.  As Chair of the Chester and Dorris Carlson Charitable Trust, Catherine worked tirelessly to continue the Carlson family legacy and their numerous philanthropic endeavors that benefited so many people in the Rochester community.  Her commitment to furthering education throughout the years by providing funding for libraries, countless scholarships for students throughout the area and books for children in our city schools has deep meaning for me, as we both shared a strong belief in the importance of learning.  Our city and our region have lost a truly special friend, caring neighbor, and a devoted philanthropist."

Catherine Carlson was a longtime supporter of WXXI, and was the Honorary Chair of the 21/21 Vision Campaign for the future of WXXI.

In recognition of her family’s generosity to WXXI, the television studio which has been home to Homework Hotline, Assignment: the World, and Need to Know was renamed The Carlson Family Studio in 2005.

WXXI President Norm Silverstein released this statement on the death of Catherine Carlson:

“With the passing of Catherine Carlson, a bright light is extinguished over the sky of Rochester.

After George Eastman and before Tom Golisano, the Carlson family, and especially Catherine Carlson, helped define philanthropy in our community.

Catherine was a donor, an advisor, an Honorary Board member, and most of all, a good friend. She especially loved the county library, WXXI and the Little Theatre, and local colleges and universities, and she helped all of them to thrive.

She will be sorely missed.”

Funeral arrangements are pending. In lieu of flowers, contributions may be made to a charity of your choice, or to the Sisters of Saint Joseph of Rochester, 150 French Road, Rochester, New York 14618.

Collection phase begins for “Images from Science 3” exhibition planned for RIT in 2019

CIS is co-sponsor of display which will celebrate extraordinary images taken by scientists and photographers around world


Sep. 7, 2018
Rich Kiley

Scientists and photographers from around the world will have the opportunity to share their scientific research, discoveries and observations of natural wonders with the launch of the collection phase of an international images exhibition scheduled for Rochester Institute of Technology in 2019.

cheap nike free run 5.0

The exhibition is being led by Michael Peres and Ted Kinsman of RIT’s School of Photographic Arts and Sciences, along with Norman Barker of Johns Hopkins Medicine—each of whom has enjoyed award-winning careers as photographers, but also as authors, teachers and industry leaders exploring and making science images.

Because of their passion for the image in science, they are coordinating the production of the third in a series of traveling exhibitions exploring the diverse field of the image in science.

"Images from Science 3" (IFS 3) is being organized to build upon the successes of the Images from Science 1 and 2 exhibitions, held previously in 2002 and 2008, respectively.

“Much has changed in the world of science, technology and explorations in the decade since those exhibitions were mounted, including the explosion of new applications of imaging technologies,” said Michael Peres, associate chair of the School of Photographic Arts and Sciences (SPAS). Peres and Andrew Davidhazy, professor emeritus in SPAS, were the original creators of the project.

“IFS 3 seeks to identify and showcase up to 75 extraordinary examples of still and moving images, animations and illustrations that reveal science in new and visually exciting ways,” added Barker, a second organizer and professor of pathology and art as applied medicine at Johns Hopkins University School of Medicine. “Similar to past projects, it will use the internet to promote the opportunity. IFS 3 will also feature a limited number of full-time student images as a part of the exhibition.” 

IFS 3 invites both new and recognized image makers who reveal science in photographs to participate in this latest collection of work. The exhibition’s goal is to produce “a traveling exposition that features extraordinary examples of still and moving images, animations and illustrations produced to explore or document a scientific process,” said Kinsman, an assistant professor of photographic sciences at RIT and a third organizer.

Seven international judges will curate the final collection of images, videos and illustrations, Kinsman noted.

IFS 3 has a number of sponsors helping provide support for the project using technology to solicit, judge, invite and display the technical excellence and creativity needed to make such photographs. In addition to RIT and Johns Hopkins University, sponsors include Carl Zeiss Microscopy, headquartered in Jena, Germany; RIT’s Chester F. Carlson Center for Imaging Science; SPAS; RIT’s School of Art; Science Source Images in New York City; and Service Photo in Baltimore, Md.

A four-color catalogue will be published by the RIT Press. The exhibition will premiere at the new RIT City Art Space in November 2019 and will then be displayed at Johns Hopkins in January 2020.

The exhibition is being dedicated to Lennart Nilsson, the late Swedish photographer and scientist noted for his photographs of human embryos and other medical subjects once considered impossible to photograph, and more generally for his extreme macro photography.

"Images from Science 1" premiered in the fall of 2002 at RIT. Launched at the infancy of the internet and digital photography, it featured 59 photographs and traveled to 22 venues in seven countries until it was retired in 2007.

"Images from Science 2" premiered in the fall of 2008 and was displayed in 13 venues before it was lost in shipping from the U.K. to the Netherlands in 2014. Both exhibitions were produced as experiments to explore the power of the internet as the sole tool used to promote, identify and ultimately display some of the world’s most powerful photographs of science at the time of their production.

RIT, NASA, JHU and STSI evaluate use of digital micromirror devices in space applications

Multiobject spectrometers (MOSs) have benefitted from the use of digital micromirror devices (DMDs) as programmable slit masks in ground-based applications because of the high reliability and accuracy DMDs provide. For this reason, knowing how DMDs would perform under conditions associated with space deployment would benefit astronomers looking for slit masks to use in MOSs on space missions.

A collaboration between Rochester Institute of Technology (Chester F. Carlson Center for Imaging Science & Department of Manufacturing and Mechanical Engineering Technology), NASA Goddard Space Flight CenterSpace Telescope Science Institute and Johns Hopkins University (Department of Physics and Astronomy & Department of Mechanical Engineering) evaluated the feasibility of using DMDs in space applications. A series of tests were performed to investigate the performance of DMDs under conditions associated with space deployment to determine their suitability for multiobject spectrometers on space missions.

Space-based MOSs would encounter the same vibration and mechanical shock that is typically associated with any launch into space, so the DMDs were subjected to vibration and shock testing. DMDs underwent vibration testing while powered off as well as in the powered on and operational state. The project utilized Texas Instruments‘ DLP7000 .7” XGA DMDs controlled using the DLi4120 Development Kit in order to test the DMDs in two different operating modes; holding a steady pattern and quickly switching among several patterns. The team then inspected the DMDs for pixels that may have changed the direction of the tilt of the micromirrors and did not detect any pixels that changed state after the vibration testing.

The DMDs were also exposed to thermal cycling and low temperature testing to determine lifetime and performance at cryogenic temperature. Among several tests conducted, the DMD micromirror array was subject to an accelerated lifetime test, where it was cycled between the on and off state for 200,000 flips – an approximation of a 10 year life of a MOS using DMD technology. Among this and the other tests conducted, the results indicated that DMDs are insensitive to low temperatures, and able to operate at temperatures as low as 78 K.

Two separate experiments focused on the result of accelerated heavy-ion radiation on DMD reliability. The DMDs were exposed to heavy-ion radiation above realistic levels for fluxes, and did not obtain any permanent damage or experience hard failure. All micromirrors that were initially disrupted from testing were cleared with the loading of a new pattern on to the DMDs, allowing the team to conclude that DMDs have limited sensitivity to heavy-ion radiation.

The combined assessment of radiation, vibration, mechanical shock and temperature testing of DMDs allowed the team to determine that DMDs are extremely reliable and robust. Overall, the results confirm that DMDs are suitable for use in both ground-based and space-based multiobject spectrometry.

student award

PhD candidate Sanghui Han is first recipient of new endowed scholarship

Apr. 23, 2018

Monday morning at USGIF’s GEOINT 2018 Symposium, Sanghui Han was awarded the first ever $15,000 K. Stuart Shea USGIF Endowed Scholarship. Han is pursuing a Ph.D. in imaging science at the Rochester Institute of Technology (RIT) in Rochester, N.Y. USGIFChairman of the Board The Honorable Jeffrey K. Harris presented the award to Han on stage.

The USGIF Board of Directors announced the creation of this new scholarship at the GEOINT 2017 Symposium in honor of K. Stuart Shea, one of the founders of USGIF and the first chief executive and chairman of the organization. The scholarship will be annually awarded to a Ph.D. student studying cartography, geography, or imaging science.

“Being a single mom and a student is challenging, especially financially,” Han said. “What this scholarship means to me immediately is some breathing room in my finances, which enables me to better conduct my research. Another facet to this scholarship are the recognition and networking opportunities, which would expand opportunities after I graduate and throughout my career by opening up possibilities for collaboration between organizations that have congruent missions. I hope the connections I make will empower me to bring together my experiences in the military and research at RIT to contribute to the advancement of geospatial intelligence.”

Han earned her bachelor’s degree in mathematics from the University of Colorado, and upon completion was commissioned as a U.S. Army intelligence officer. She began pursing her master’s degree in imaging science through RIT while deployed to Afghanistan and continued her studies throughout her Army tenure. She completed her master’s degree toward the end of military career and then began pursing a Ph.D. in imaging science full-time. Han’s research develops a framework for predicting utility of spectral images to facilitate the design of imaging systems. She hopes this research can help build simple, flexible systems optimized for various information requirements.

“Developing advanced tradecraft is a priority for the Foundation and the USGIF Board is very pleased to award the first K. Stuart Shea USGIF Endowed Scholarship to Sanghui,” Harris said. “Her career trajectory has an important connection to the GEOINT mission having served with the U.S. Army as a Joint Reconnaissance Officer in South Korea. This hands-on experience provides an excellent opportunity to help ensure that her research in improved precision image modeling can translate directly into positive GEOINT mission impact. Recognizing the substantial contributions to USGIF by former chairman Stu Shea, this scholarship reaffirms his leadership principal to actively build the community.”

This scholarship is part of the overall USGIF Scholarship Program. The full list of 2018 scholarship recipients will be announced this summer. Learn more about the USGIFScholarship Program here.
