Abstract : The holographic stereogram (HS) consists of an ensemble of juxtapositioned transform-holograms made from photographic transparencies of a scene. The viewer looks into the HS, as with a conventional hologram, and sees a virtual image reconstruction accurately rendering the object space. In this treatment the two basic types are reviewed: one using a single exposure with a fly's-eye lens and the other a temporal sequence of photos. Their conceptual relationship to Lippmann's integral photograph and Gabor's hologram is explained. Analyses are presented of scaling and resolution for the sequential type of HS. Up and down scaling as well as vertical exaggeration can be controllably obtained. Using a simple Gaussian beam analysis, a formula for the angular resolution of the HS is found. (Author)
