A method of analyzing bulk diffusers based on diffraction theory is developed. Bulk diffusers are often used to diffuse the incident light in projection screens. They are modeled as glass spheres randomlyh suspended throughout a plastic substrate. The theory accounts for a distribution of sphere diameters. The method of analysis and results are presented. With this method of analysis, bulk diffusers can be designed with optimal optical performance.
