The generalized holographic stereogram

A general model for holographic stereograms in the context of discrete and continuous optical systems is presented. Building from a simple, highly constrained model, restric-tions on the viewer's horizontal position and depth, the size and location of the plane of the stereogram's slits, the spatial resolution of the points in the imaged object, and the optical properties of the projection screen are relaxed one by one. Emphasis is placed on accurate modeling of the stereogram and on the correspondence between the photographic capture, holographic recording, and final viewing geometries. Bandlimiting and anamorphic distor-tion techniques useful for producing artifact-free images are presented. Discussion centers on horizontal parallax only, flat format, computer generated stereograms, but general con-clusions applicable to other stereogram types are drawn. Specific examples of stereograms created using these techniques are shown and discussed
