Surface-relief hologram recording in silver halide gelatin emulsion

The processing procedures for surface relief holograms recorded on silver halide emulsions are presented. The most promising methods have been investigated and compared. The aim is to develop and optimize methods for obtaining relief structures on silver halide gelatin emulsions for holography at rather high spatial frequencies. Such a relief pattern can then be used for making a metallic matrix. The main advantage of using a silver halide material, instead of photoresist material, is the favorable sensitivity characteristics over the whole visible spectrum of silver materials.© (1993) COPYRIGHT SPIE--The International Society for Optical Engineering.
