This paper discusses holographic methods for obtaining diffusers and microlens rasters on silver halide photographic emulsions. The gelatin-photolysis method in which short-wavelength UV radiation acts on the photosensitive layer and methods of chemical and photohardening of photographic emulsions processed with dichromate solutions are used as technologies for creating relief-phase structures.
