摘要：
A method for making high diffraction efficiency holograms from dichromated gelatin material including the steps of curing the material for a specified time under controlled temperature and humidity conditions, placing a dye spot on the cured material, measuring the extent of diffusion of the dye spot after a predetermined time, replacing the material into the curing conditions, repeating the method until dye spot diffusion of a predetermined size occurs, and using the material to make holograms.
