Method of producing stable holograms in dichromatic gelatin

摘要

A method of developing a holographically recorded interference pattern in a dichromatic gelatin structure is provided. The process includes developing the hologram pattern by hydration and dehydration, baking the developed hologram pattern at a temperature equal or above 120 DEG C. for approximately 24 hours, rehydrating the developed hologram and dehydrating the developed hologram at a temperature of approximately 60 DEG C. for approximately 48 hours until the design wavelength response is attained to provide a stabilized hologram.
