<p>A projection engine architecture for use with liquid-crystal-on-silicon semiconductor imager devices is described. This projector architecture relates to rear projection television and computer monitor applications, wherein image resolution is higher and image size is larger than is practical with cathode ray tube based technologies. The optical architecture disclosed includes a high speed light collection stage wherein luminance from an arc lamp is collected and condensed, an illumination stage wherein the luminance is ideally transformed for presentation to an imaging stage comprised of a triad of three perpendicular polarization beamsplitter cubes and attendant color processing components that form a solid prism assembly. Central to the architecture are means for eliminating the deleterious effects of waste light created by polarization and color separation components within the imaging stage.</p> |
