Kehar Singh (Short Bio)
Presently, Hony. Professor in the ‘Optics and Photonics Center’ IIT Dehi, Prof. Kehar Singh served as a faculty member of IIT Dehi during the period 1965-2011 in various capacities including Head Physics Dept. and Dean Postgraduate Studies and Research IITD. As an academic visitor at the Imperial College London during 1969-1970, he carried out research on partially coherent imaging, and on holography at the N. P. L. Teddington (UK). He served as CLUSTER Chair at the EPFL, Lausanne in Dec.2002.
As a researcher and educator, he created infrastructural facilities at the IITD in his areas of interest: Information optics, photorefractive nonlinear optics, dynamic and digital holography and speckles, optical correlators, holographic storage, and optical cryptography. He mentored 31 doctoral-, and 80 M. Tech. (Appl. Opt.)-, students, and has published extensively, having authored / co-authored nearly 300 peer reviewed research papers, approx. 75 review articles in books and journals.
Prof. Singh served as Assoc. Editor, Optics Express (2015-2021), Int’l advisory member, Editorial board of Optical Review (Japan, 1994-2008), Member editorial boards: Optics & Lasers in Eng. (1999-2006), and J. Optics (India/Springer,1974- to date), He also served as a chair/member several international conferences. Besides having served as a consultant to some industries/organizations, he has also been a consultant on security holograms to some state Govts. in India. and served as a member of the Executive Committee, National Photonics Program DRDO.
Prof. Singh’s awards and honors include: OPTICA Emmett Leith medal (2025), S. S. Bhatnagar Prize (1985), Galileo Galilei medal (2001, ICO) -, Opt. Soc. India Award, Life Time Achievement Award OSI (2007), and Golden Jubilee ‘Distinguished Service’ Award of IIT Delhi (2011). He is a Fellow of OSA (now OPTICA), SPIE, INAE, and Distinguished Fellow of OSI, and served as President OSI (1991-1994), Director, II Winter College in Optics (ICTP, Trieste, Italy (1995), Chairman, Research Council, IRDE Dehradun (2013-2018), Member Research Council, NPL New Delhi (2017-202
