Contemporary Holography

This book is unique in covering most of the developments on optical holographic techniques since holography’s invention in 1947 by Dennis Gabor. Starting from conventional holography with photopolymer recording techniques to CCD(Charge Coupled Device)-based digital holography, this book covers the spectrum of contemporary holographic techniques. The first chapter deals with conventional holographic methods using photographic plates in both in-line Gabor holography and off-axis holography. Then the second chapter covers principle and experimental techniques of the Conoscopic holography technique, and the third chapter deals with Computer generated holography. The fourth chapter discusses basic principles of dynamic holography using photorefractive crystals where the theory and experiments show how the photorefractive effect is used for dynamic recording of holograms. The fifth and sixth chapters extensively discuss the fundamentals of digital holography and unconventional coherence holography. In digital holography, two types of phase shifting methods which are dynamic and geometric phase shifting digital holographic techniques are elaborated with practical examples. Then, in the sixth chapter, the unconventional coherence holographic method describes a new holography using incoherent light sources.

This book is intended for advanced undergraduate and first-year graduate-level students, as well as researchers looking for a complete resource in holography techniques.

C. S. Narayanamurthy is currently working as a Senior Professor with the Department of Physics, Indian Institute of Space Science and Technology (IIST, Valiamala (PO), Trivandrum, India. Prof. Narayanamurthy did his PhD from IIT Madras in the area of Laser Speckle Interferometry. He then carried out his post-doctoral research in dynamic holography using photorefractive crystals at the Imperial College, London, UK during 1990-91. He works mainly in the area of Applied Optics (Holography, Optical Metrology) and Adaptive Optics (Wavefront sensing, Imaging through turbulence, etc). Prof. Narayanamurthy has published more than 70 papers and is a recipient of the 2022 Galileo Galilee Award instituted by the International Commission for Optics (ICO) for his contributions in Applied and Adaptive Optics. He is also currently the President of the Optical Society of India and a Distinguished Fellow of the Optical Society of India.
