THE TECHNICAL BASIS OF MASS-PRODUCING LIPPMANN HOLOGRAMS

The characters and applications of gelatin plates which have been successfully invented by the authors are introduced. Simplified process of producing DCG hologiaphic recording materials is presented. The mechanism of hologram formation in DCG is discussed. The holographic characters of DCG, such as diffraction efficiency, curves of exposure charaters, exposure sensitivity, modulation transform function, resolution, film thickness, etc.,are measured. The conditions of mass-producing Lippmann hologram are optimized. The Lippmann holograms can be used for adornments, souvenirs and advertisements.
