Novel methods for the creation of silver free images in holography using conventional silver-halide emulsions
1993
The authors discuss the area of silver halide process technology associated with the formation of voided gelatin conventionally known as silver halide sensitized gelatin (SHSG). Comparative studies have shown that this method is capable of creating master holograms (in transmission mode) that are virtually free of the grain scattering noise that besets conventional silver halide gelatin (SHG) holograms. Despite intuitive conclusions that such noise reduction must be associated with a proportional reduction of diffraction efficiency, it is found that holograms of high efficiency and simultaneous low noise are achieved.
