Rehalogenating bleaches for photographic phase holograms: the influence of halide type and concentration on diffraction efficiency and scattering.
The use of a rehalogenating bleach without fixing to produce photographic phase holograms has been advocated on the grounds that emulsion shrinkage is minimized. It has also been reported that high diffraction efficiencies can be obtained with low scattering. Experimental results are presented which show that the diffraction efficiency and scattering obtained with such a bleach as well as its mode of operation depend very much on the choice of the alkali halide added to the bleach and its concentration. The processes responsible for the effects observed are discussed.
