Bleached silver halide volume holograms recorded on Slavich PFG-01 emulsion: the influence of the developer

摘要

Bleached holograms are one of the most interesting techniques used to produce phase holograms of high quality on photographic emulsions. Of particular interest is the method of fixation-free rehalogenating beaching. In this paper we sill study the influence of the development step in the bleaching process applied to Slavich PFG-01 emulsion, a red-sensitive fine-grained emulsion from the Slavich Company. We will show that the development influences the optimum concentration of potassium bromide in the bleach solution. We will also show that good results can be obtained by using Slavich PFG-01 plates for a wide variety of developers; in the case of the CW-C2 developer a diffraction efficiency of over 70% was reached.
