Light scattering in photographic materials for holography.

A simple system for measuring the scattered flux from fine-grained photographic emulsions is described. With this system the Wiener spectrum of sample emulsions is measured for samples varying in grain size, thickness, silver-to-gel ratio, development time, and transmittance. It is shown that the measured results agree well with what is to be expected on theoretical grounds and that the functional form of the scattered light is well described by an overlapping-circular-grain model of the emulsion.
