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.
