Phase Error Correction in Digital Holographic Imaging
James Fienup, Robert E. Hopkins Professor of Optics, The Institute of Optices,University of Rochester, United States
Abstract: Digital holographic imaging has applications across multiple disciplines, including microscopy and remote imaging. In many situations phase errors arise due to the propagation medium (atmospheric turbulence or tissue, for example) or when stitching together a synthetic aperture (due to time-varying motions of the object, of the data collection array, or of the phase of the reference beam, for example), and the result is a blurred image. This paper reviews some of the phase-error correction algorithms that allow a diffraction-limited image to be reconstructed from the collected data.

Bio: James R. Fienup received his PhD in Applied Physics from Stanford University. He was a Senior Research Engineer at Environmental Research Institute of Michigan (ERIM) and Veridian Systems, Ann Arbor, MI, until 2002, and is the Robert E. Hopkins Professor of Optics at the University of Rochester. He is a member of the National Academy of Engineering, is a Fellow of the Optical Society of America 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, the International Prize in Optics for 1983 by the International Commission for Optics, and the Emmett Leith Medal for 2013 by the OSA. He was a Distinguished Visiting Scientist at the Jet Propulsion Laboratory in 2009. 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, and Associate Editor of Optics Letters.
Prof. Fienup’s research centers on obtaining images with finer resolution. He developed phase retrieval and image reconstruction and restoration algorithms for unconventional imaging, lensless coherent imaging, wavefront sensing, and aberration correction. Application areas spanned nano-imaging with coherent x-ray diffraction, digital holography, correcting astronomical telescopes, imaging through aberrating media, synthetic-aperture radar (SAR), and biomedical imaging. He also contributed to diffractive optical elements, image quality for sparse-aperture systems, SAR moving-target detection, and computer-generated holograms. He has over 220 publications and 5 patents.

See Through Optical Architectures for Wearable Displays,
Bernard Kress, Optics Lead, Advanced Technology Team, Google Glass Project, Google [X], USA
Abstract: HUDs (Head Up Displays) and HMDs (Helmet Mounted Displays) have been with us for a few decades, providing exceptional optical performances for specialized defense applications. On the other hand, consumer electronics HMDs (Head Mounted Displays) have been lingering as personal gadgets for a mere decade. But recently, major companies have launched consumer compelling head mounted display solutions integrating both hardware, operating system as well as content, unlocking the decade long consumer HMD status-quo.
As a result, we are witnessing today a fragmentation of the HMD market into various categories which have their very own specificity in terms of functionality, hardware and content. Such fragmentation is responsible for defining new distinct market segments such as consumer near to eye displays, social smart glasses, gaming headsets, as well as professional (engineering and technical) HMDs, specialized (medical, law enforcement, firefighting) HMDs and of course the previously existing defense market. We will be reviewing the different type of optical hardware used in such devices.

Bio: For over 20 years, Bernard has made significant scientific contributions as researcher, professor, consultant, advisor, instructor, and author, making major contributions to digital micro-optical systems for consumer electronics, generating IP, and teaching and transferring technological solutions to industry. Many of the world’s largest producers of optics and photonics products have consulted with him on a wide range of optics and photonics technologies including; laser materials processing, optical security, optical telecom/datacom, optical data storage, optical computing, optical motion sensors, pico- projectors, light emitting diode displays, optical gesture sensing, three dimensional remote sensing, digital imaging processing, and biotechnology sensors. Bernard has generated more than 30 international granted patents. He has published four books, a book chapter, 102 refereed publications and proceedings, and numerous technical publications. He has also been Involved in European Research Projects in Micro-Optics including the Eureka Flat Optical Technology and Applications (FOTA) Project and the Network for Excellence in Micro-Optics (NEMO) Project. Bernard is currently the Optics Lead in the Advanced Technology Team at Google Glass Project
