Dr. Johnson has been a Visiting Scholar at the Center for Imaging Science for the past four years. His current research involves work with the Dead Sea Scroll Team and the Petra, Jordan Papyrus Project.
Dr. Johnson's research and publications have always been centered on the application of scientific techniques such as digitally enhanced xeroradiography, neutron activation, photomicroscopy, petrographyic analysis, infared, ultraviolet and most recently, digital imaging restoration technology. Images of fragments are digitally clarified using digital cameras, infared and ultraviolet to assist textual scholars to more easily translate degraded text images.
He received a B.S. degree from Kutztown University, an M.A. degree from Columbia University, and the Ph.D. degree from Pennsylvania State University.

Dr. Roger Easton
Dr. Easton is an Associate Professor at the Center and has taught classes in Imaging Mathematics (linear systems for imaging), Digital Image
Processing, and Optics. He has written a computer program for illustrating the concepts of digital image processing and linear systems (e.g., convolution, and Fourier transforms), sampling, quantization, and of physical optics (interference, diffraction, and holography).
In addition to teaching, Dr. Easton's research interests include the work with the Dead Sea Scrolls, as well as coordinating transformations in image processing, and digital halftoning and digital holography. You can find discussion of the Scrolls work in Optics and Photonics News, 8(8), pp. 30-34, August 1997.
He received M.S./Ph.D., Optical Sciences, from the University of Arizona, an M.S., in Physics, from the University of Maryland and a B.S., Astronomy from Haverford College
