Abstract

Reflectors suitable for use in rear projection television systems, LCD projectors and stereoscopic effects devices, and numerous other applications, include a substrate having a microprism or lenticulated sheet structure, and in which one or more surfaces are made reflective through the use of polishing or the addition of a reflective coating. The reflective surface or surfaces may include a planar rear surface of the substrate, in which case the remaining intersecting front surfaces of the sheet are arranged to expand, shift, or reduce an image incident on the front surface of the sheet as the rays of the image pass through the sheet and are reflected by the reflective surface. Alternatively, the reflective surface or surfaces may be intersecting front surfaces and/or curved surfaces of the sheet and the generally planar rear surface of the sheet may be treated or shaped to expand, shift, reduce, or otherwise modify the image reflected by the angled or curved reflective surfaces. In the case where the angled surfaces include pairs of intersecting surfaces, at least one of the surfaces in each pair may be left transparent so as to transmit light and thereby provide a beam splitting effect.
