Читать книгу Optical Cryptosystems - Naveen K. Nishchal - Страница 9

First of all, I would like to thank my mentors at the Indian Institute of Technology (IIT) Delhi during my doctoral studies. I especially thank my PhD supervisors, Professor Kehar Singh and Professor Joby Joseph, for introducing me to the exciting world of optical information processing research. Over the years they have been much more than just a thesis advisor to me. I am sure that they will be happy to see this book out in print. I must thank Dr G Unnikrishnan from IRDE Dehradun with whom I have had numerous discussions. I wish to extend my sincere thanks to Dr A K Gupta, Ex-Director IRDE Dehradun and Professor R S Sirohi, Ex-Director, IIT Delhi, for their encouragement.

My colleagues at IIT Patna deserve due acknowledgments for their encouragement. I acknowledge my gratitude to IIT Patna for providing facilities and a congenial environment. I must thank my colleagues from abroad, Professor Bahram Javidi, University of Connecticut; Professor John T Sheridan, University College Dublin; Professor Thomas J Naughton, Maynooth University; Professor Ayman AlFalou, ISEN/Yncrea; Professor Christian Brosseau, Universite Britagne Occidentale; Professor Cornelia Denz, Universitat Muenster; Professor Yan Zhang, Capital Normal University; Professor Takanori Nomura, Wakayama University; Professor Osamu Matoba, Kobe University; Professor Guohai Situ, Shanghai Institute of Optics and Fine Mechanics; and Professor Xiang Peng, Shenzhen University with whom I have had the opportunity to interact and learn the subject.

I must thank Elsevier, OSA, and SPIE for allowing me to reuse some of their diagrams/images published in various journals. Thanks are due to Jessica Fricchione, Poppy Emerson, and Sarah Armstrong from IOP Publishing, UK, for guiding me on many issues while preparing the manuscript.

I wish to extend my sincere thanks to all my students, Dr Sudheesh K Rajput, Dr Isha Mehra, Dr Dhirendra Kumar, Dr Areeba Fatima, Alok K Gupta, Avishek Kumar, Praveen Kumar, and Yatish. My continuous interactions with them have led me to a deeper understanding of the subject. They helped me in preparing this manuscript and drawing some of the difficult diagrams.

Finally, I owe a lot to my family—particularly to my wife Rinki and my son Anvit for allowing me to spend long hours in preparing this manuscript and for their support throughout. I also thank my other family members in appreciation of their patience, encouragement, and constant support while this manuscript was being prepared.
