This article describes the basic physics of several types of holograms and discusses different recording materials in use. Current and possible future applications of holograms are described as well as their large-scale production. (Author)

Describes various methods of rendering visible the paths followed by a laser beam for direct viewing or for photographic purposes. (Author/GS)

Outlines what a hologram is, the main types of holography, and how a simple system producing a white light reflection hologram can be set up in a school physics laboratory. Discusses the basic optics of the hologram and procedures and materials for making holograms in school. (YP)
