Optical Cryptosystems. Naveen K. Nishchal

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.
