Image Reconstruction and Aberration Sensing by Phase Retrieval

James R. Fienup, Ph.D.,
Robert E. Hopkins Professor of Optics,
Professor of Electrical and Computer Engineering
University of RochesterAbstract: Phase retrieval has been under development for image reconstruction and wavefront sensing. Application areas include astronomy, space-object imaging with both active-coherent and passive-incoherent illumination, wave-front and telescope-misalignment sensing (e.g. Hubble and James Webb space telescopes), and 3-D coherent imaging. This talk will review some of the highlights of phase retrieval development and some recent advances in phase retrieval approaches and algorithms that have occurred in the last few years.Biography: James R. Fienup received an A.B. in physics and mathematics from Holy Cross College (Worcester, MA), and M.S. and Ph.D. (1975) degrees in Applied Physics from Stanford University, where he was a National Science Foundation Graduate Fellow. He performed research for 27 years at the Environmental Research Institute of Michigan and Veridian Systems, where he was a Senior Scientist. He joined the faculty at the University of Rochester in 2002 as the Robert E. Hopkins Professor of Optics. He also holds positions as Professor, Center for Visual Science, Professor of Electrical and Computer Engineering, and Senior Scientist, Laboratory for Laser Energetics. Professor Fienup is a Fellow of the Optical Society of America (OSA) and of the International Society for Optical Engineering (SPIE), and is a Senior Member of IEEE. He was awarded the Rudolf Kingslake Medal and Prize for 1979 by the SPIE and the International Prize in Optics for 1983 by the International Commission for Optics. He was Editor-in-Chief of the Journal of the Optical Society of America A, 1997-2003. He previously served as Division Editor of Applied Optics - Information Processing, Associate Editor of Optics Letters, and Chair of the OSA Publications Council of the OSA.Professor Fienup's research interests center around imaging science. His work includes unconventional imaging, phase retrieval, wavefront sensing, and image reconstruction and restoration. These techniques are applied to passive and active optical imaging systems, synthetic-aperture radar, and biomedical imaging modalities. His past work has also included diffractive optics and image quality assessment. He has over 180 publications and 4 patents.Host: B. Keith Jenkins, jenkins@sipi.usc.edu
