Abstract
Assembly 10 is formed of base and cover plates 12 and the 16 with dichromated gelatin holographic exposure layer 20 therebetween. Liquid monomer is placed in the assembly and is polymerized to solid polymer layer 22 to form a solid assembly for holographic exposure of dichromated gelatin layer 20. After exposure, heating permits removal of cover plate 16 and polymer layer 22 for subsequent development of the latent image in dichromated gelatin holographic exposure layer 20.
