A holographic stereogram synthesis system was experimentally produced. This system uses a transmission type liquid crystal display as a light modulator. The holographic stereogram synthesized with this system is a laser light reconstruction type. A sheet of exposed hologram film contains 180 kinds of pictures generated by the ray tracing technique. The sizes of used films are about 70mm×300 mm. It is possible to make one holographic stereogram within 50 minutes. This time does not include picture generation time by the ray tracing technique. A reconstructed picture can be observed clearly in a bright room. when a 5mW He-Ne laser is used.
