The Optical Society Fellows Class of 2020 includes two JOSA A topical editors, Yangjian Cai and Jennifer Hunter. Yangjian was cited “for significant contributions to optical coherence structure engineering and their applications.” In his work at JOSA A, he covers atmospheric optics, which is more and more concerned with coherence theory and structured light. This important and growing area is in good hands. Jennifer was cited “for the development of ophthalmic imaging systems that provide unprecedented insight into the function and structure of the retina.” She covers visual and physiological optics for us at JOSA A. If you are building instruments to reveal the mysteries of visual systems, you want Jennifer to handle your paper. Her deep expertise combined with her broad scholarly perspective not only ensures quality at JOSA A but lends critical insights in the review process, resulting in improved papers. Congratulations to Jennifer and Yangjian on this well-deserved recognition.

David Fischer has joined the team of JOSA A topical editors in the area of Fourier Optics and Coherence. He will replace outgoing editor Greg Gbur, who completes his second term as JOSA A topical editor at the end of January. Greg has been a wonderful colleague, capable of covering a wide array of topics when needed and always willing to help with works on the boundaries of our usual coverage. Greg’s manifold talents and interests are expressed beyond JOSA A in his scientific publications, ranging from imaging to singular optics, his two textbooks, his popular science blogs and articles, and his wonderful recently published popular science book [1]. I am deeply grateful to Greg for his time at JOSA A and look forward to his work in optics and beyond.

Fourier Optics and Coherence

David Fischer is a Senior Optical Scientist at the NASA Glenn Research Center in Cleveland, Ohio, USA. He received a B.S. and M.S. in Electrical Engineering from the Johns Hopkins University, USA, and a Ph.D. in Optics from the Institute of Optics, University of Rochester, USA, under the guidance of Professor Emil Wolf. He develops optical diagnostic imaging and sensor technologies, with an emphasis on human health and environmental monitoring applications. His work encompasses all phases of development, from first principles, to instrument design and construction, to algorithms for signal estimation and image reconstruction, and lies at the intersection of several disciplines, including computational imaging, inverse scattering, physical optics, and coherence theory. He has been awarded both the NASA Exceptional Scientific Achievement Medal and the NASA Exceptional Technology Achievement Medal, as well as a R&D 100 Award, for his work, and he holds several patents.
