Chester F. Carlson Center for Imaging Science
My research involves both imaging at the nanometer level and building prototype nanomaterials-based imaging devices. We have a suite of microscopes in the NanoImaging Lab that are used to image at the nanolevel, including a transmission electron microscope, a scanning electron microscope with full X-ray microanalysis capabilities, and a scanning probe microscope capable of atomic level imaging on material surfaces. In addition, we have a variety of support equipment for sample preparation. We also have facilities for fabricating imaging devices and evaluating their electro-optical characteristics. Currently, we are building image displays in which the emitting materials are quantum dots. The emission from these materials can be tuned by adjusting their size so as to achieve a full-color display.

SIMG 711 - Basic Principles of Imaging Science I (4 credits) This course provides the student with a basic understanding of the scientific principles associated with electromagnetic radiation propagation, image capture and formation, and display of images. An end-to-end treatment of an imaging system shall be employed to illustrate the interrelationship among the concepts introduced throughout the course. System analyses include the use of modeling concepts and image quality metrics to demonstrate how the concepts developed in Linear Image Mathematics can be used in concert with concepts in this course to describe and assess a simple imaging system. (graduate level) (Both in-class and distance-learning versions)
SIMG 713 - Noise and Random Processes (4 credits) The purpose of this course is to develop an understanding and ability in modeling noise and random processes within the context of imaging systems. The initial part of the course is an introduction/review of basic probability theory needed for the middle part of the course, which introduces random processes. The final part of the course will demonstrate the application of the textbook material to the understanding of signal and noise in imaging systems. At the completion of the course, the student should have the ability to model signal and noise transfer within a multistage imaging system.
