Abstract

Generally, the present disclosure describes a compact optical integrator that provides an increased path length for a beam of light in a compact projection system. The increased path length can improve the uniformity of the light passing through the compact projection system, with a minimal increase in the size of the system. The light can be homogenized by mixing light entering the integrator from different regions of the input area. The compact optical integrator can be positioned in the optical path between a light source and a spatial light modulator, such as a liquid crystal display (LCD) or a digital micro-mirror (DMM) array.
