Abstract

In this paper, the Wiener spectra of experimental emulsions with homogeneous cubic grains are compared with the Wiener spectra of commercial emulsions which have the same mean radius as the experimental emulsions but have a greater range of grain sizes. The experimental noise spectra are then compared with the theoretical noise spectrum of an ideal emulsion.
