WUHAN, China (May 30, 2019) - Wuhan Optoelectronics Forum No. 158 was successfully held in Auditorium A101 at Wuhan National Laboratory for Optoelectronics (WNLO) in the afternoon of May 30. Prof. Partha P. Banerjee from University of Dayton delivered an exciting talk entitled Taking Correlation from 2D to 3D: Optical Methods and Performance Evaluation. Dr. Ling Fu, from WNLO chaired the forum, and, awarded Prof. Partha P. Banerjee the forum medal.
Correlation of two dimensional (2D) images using photorefractive materials are first reviewed. The performance of a joint transform correlator based on photorefractive beam coupling is analyzed by determining the dependence of typical figures of merit such as the discrimination ratio, peak-to-correlation plane energy ratio, peak-to-noise ratio, etc. on the photorefractive gain coefficient and beam power ratio using typical reference and signal images. Furthermore, correlation of three dimensional (3D) images is introduced as the correlation of their 2D digital holograms. Critical figures of merit used for assessment of 2D correlation of images are applied to the correlation of holograms. Figures of merit are applied for object height identification using digitally recorded holograms as the 2D images. Results show the potential for accurate object height recognition based on obtained results corresponding to figures of merit as an assessment metric.
Partha P. Banerjee is Professor and Chair of the Department of Electro-Optics and Photonics (EOP) at the University of Dayton (UD), and Professor of Electrical and Computer Engineering (ECE) where he was Chair from 2000-2005. Prior to UD, he was with the University of Alabama in Huntsville from 1991-2000, and with Syracuse University from 1984-1991. His research interests include digital and dynamic holography, photorefractives, optical metamaterials, nonlinear optics, and optical trapping. He is Fellow of Optical Society of America (OSA), International Society of Photonics Engineers (SPIE) and the Institute of Physics (FInstP), and senior member of Institute of Electrical and Electronic Engineers (IEEE). He received the NSF Young Investigator Award in 1987.
At UD, Dr. Banerjee established the Holography and Metamaterials (HaM) lab. He has organized the OSA international meeting on Digital Holography in 2010, 2016 and 2019, and was Topical Editor for Applied Optics from 2012-2016. He was also Chair of the OSA Environmental Monitoring Committee from 2014-2016. To date, Dr. Banerjee has published 5 textbooks, over 135 refereed journal papers, and over 150 conference papers/ presentations, and holds 1 patent. He has supervised 24 PhD dissertations and 16 MS theses. He also actively participated in the international cooperation of the School of Engineering Sciences (SES) and the School of Optical and Electronic Information (SOEI) of Huazhong University of Science and Technology (HUST), and established new programs for student exchange and talent cultivation.
