Paper Abstract

We present an equivalent bilinear system to a microdensitometer that describes the transformation from the light-amplitude- transmittance of a film sample to the light intensity output of microdensitometer. This system is characterized by a bilinear transfer function which does not depend on the sample being measured. The expression for mean intensity transmittance is obtained in which the response to the mean amplitude transmittance of a sample can be linearized while the response to the film grain noise remains bilinear.
