This is a book about the three-dimensional imaging technique of holography. It covers the fundamental physical and optical principles of using diffraction to record and reconstruct images, human perception, and the history of holographic imaging with an approachable explanation of both basic and advanced holographic concepts. This authoritative work focuses on practical holography, including methods for white light illumination, full color holography, and holographic recording of natural scenes. The book promotes a hands-on approach to making holograms and an understanding of why and how they work.
