Abstract
A combined viewer and projector for display of holographic films prerecorded in cylindrical configuration at prespecified nominal radius of curvature. The projector and the viewer sections of the apparatus each include mirrors positionable by an operator for defining film-illumination light path having a length corresponding to the path length needed to illuminate the film at the prespecified radius. The film preferably is packaged in a cassette which includes a pair of laterally spaced spools which may be driven in either direction by the apparatus and a frame which guides the film through an arcuate path of prespecified radius of curvature.
