Abstract

A light recycler (34) for use in color projection display systems (38, 48). The light recycler (34) redirects light reflected by a color wheel (35, 41) of the projection system (38, 48) to increase the light output of the projection system. The light recycler (34) is capable of setting the desired numerical aperture of the light source beam, as well as providing the desired spatial distribution of light in terms of intensity and angle. This improves the light uniformity brightness of the image displayed by the projection system, and improves the efficiency of the system. The light recycler (34) includes at least one substantially planar optical element array receiving the non-uniform light from the light source. The optical element array includes an optically transmissive substrate and a plurality of optical micro-elements formed in the substrate. The micro-elements act together to produce an output light beam having a desired cross-sectional area and spatial distribution of light intensity and angle.
