METHOD AND APPARATUS FOR PRODUCING HOLOGRAMS UTILIZING A PLURALITY OF SHORT FOCUS CONVEX LENSES

摘要

A plurality of short focus convex lenses are irradiated with a coherent beam of light. The coherent beam of light is diffused by the lenses and the diffused light is directed to a storage plate. The storage plate is irradiated with a reference beam of light in a manner whereby the reference beam of light interferes with the diffused beam of light.
