Holography, a method of photography that produces highly realistic images, fully three-dimensional, with the normal parallax relations of the actual object, is described. Basics of the theory are presented from both a mathematical and a physical viewpoint. Various areas of application are given, including three-dimensional displays, complex spatial filtering, hologram interferometry for nondestructive testing and metrology, product authentication and counterfeiting security, holographic optical elements, and imaging through inhomogeneities using holographic phase conjugation. The various forms of white light viewable holograms are described, including the Denisyuk or volume type, the Benton or rainbow type, and the integral type. The diffractive properties of holograms are analyzed, including Bragg diffraction, i.e., diffraction from a volume hologram. The construction of commercial display holograms is discussed. The present state of commercial and artistic holography is discussed, along with expected future developments.
