title: Nonlinear effects of the recording material on the image quality of a Fourier hologram.
abstract: A new representation for the D log E curve for photographic emulsions, based on the Fermi formula, is presented. This representation uses easily measured photometric parameters and is conveniently adapted for different kinds of absorption holographic recording materials. The corresponding transmittance-versus-exposure curve is used to calculate the influence of film nonlinearity on Fourier-transform hologram-recording parameters.
