Abstract

A new variant of our general reflector analysis program includes special computations to simulate the behavior of light after striking a diffusing surface. Each ray is converted at that surface, into a group of rays whose angular distribution is dictated' by the surface properties. The program accepts an experimentally determined "map" of the reflected beam profile for a given material, and uses this map to generate a group of reflected rays for each incident ray. Computed light distribution is compared with experimental values for a simple example of diffusely reflecting bead-blasted aluminum.
