Abstract
The scattering from surfaces whose profile has a center of symmetry is considered. It has been reported that the diffuse component displays a very narrow peak in the specular direction. We show that if the portion of the surface illuminated has a length L. the width of this peak is of order X I L .andthat the enhancement doubles the diffuse intensity in the specular direction. We also show that, by phase-shifting one half of the pupil, it is possible to destroy the effect and deplete the intensityin this direction. These effects are difficult to detect experimentally and, to alleviate this situation, we have also considered the scattering from diffusers which are symmetric in sections. They have similar scattering characteristics to those in the previously considered case, but the enhancement is easier to detect experimentally. Some random surfaces with symmetries have been prepared, and we present experimental results to support our conclusions.
