ABSTRACT:
An optical reflector is positionable between one or more light sources and one or more spatial light modulators (SLM's) within a digital projection system. The optical reflector includes a substrate having a surface to render non-uniform light from the light sources to the SLM's more uniform with one reflection off the substrate, and a number of facets within the surface of the substrate.
