Paper Abstract

Silver halide (sensitized) gelatin has the sensitometric response of silver halide emulsions and the holographic characteristics found in dichromated gelatin. We have demonstrated high diffraction efficiencies with low emulsion scatter noise using commercially available emulsions and standard photographic processing. Like DCG this process suffers from emulsion thickness variations which are related to sensitizer concentration and processing conditions. We describe chemical methods which permanently modify the gelatin binder to minimize thickness variations in gelatin emulsions. The technique also can be used to stabilize the processed hologram to adverse environmental effects.
