Abstract

A model for the transmission of light through a thin diffuser is presented which accounts for the angle of incidence of an input plane wave. This model is then used to make several illustrative calculations of the spectral intensity of the light scattered by the diffuser for arbitrary correlation lengths. In these calculations, it is assumed that the diffuser roughness is represented by a jointly normal random process. The spectral intensity is evaluated analytically for a triangular correlation function and arbitrary diffuser roughness. Experimental curves are also presented of the radiation patterns of ground glass for a wide range of illumination angles with the output angle 0 being swept over the range ± 90°.
