Paper Abstract

An investigation that the diffraction efficiency of dichromated gelatin (DCG) holograms is stable in the high humidity (RH equals 85%) environment is reported. In this study, the amino group, one strong absorbing humidity groups of gelatin in DCG, is modified with acetic anhydride and changed into weak absorbing humidity groups, amide groups. The procedures of the molecule enclosure did not obviously affect the diffraction efficient of DCG holograms.
