摘要： A method for recovering polarization comprises the steps of: guiding light having first and second polarizations in a forward direction along a light path; passing the guided light having the first polarization out of the path; reflecting the light having the second polarization backwardly and forwardly along the light path; transforming the reflected light during the reflecting step to have the first polarization; and, passing the light transformed to the first polarization out of the path, enabling more of the light having the first polarization to be passed out of the path. The method can be implemented with a light integrator, a reflecting polarizer, at least one reflective surface that further reflects the reflected light back toward the reflecting polarizer and a quarter wave plate positioned in the light path. The method and apparatus can be used in an illumination system for a liquid crystal display imager.

A relay lens system directs the output of the first stage imagers into a second polarizing beam splitter. The second polarizing beam splitter is configured to direct light of the second polarization onto the first channel second stage LCOS imager and direct light of the first polarization onto the second channel second stage LCOS imager.

摘要： A lens system for use in a two-stage projection system that relays light output from a first imager on a pixel-by-pixel basis onto a second imager (e.g. an LCOS). The lens system includes a double gauss lens set having a distortion of less than about 0.015% with at least about 90% of the light energy of a specific pixel projected within about a 15.4 micrometer square. Thus a projection system that enhances the contrast ratio for video images, particularly in the dark state, and reduces contouring artifacts, can be achieved.

A first imager is configured to modulate a light band on a pixel-by-pixel basis proportional to gray scale values provided for each pixel of the image to provide a first output matrix.

A relay lens system having a single-gauss lens set and a mirror positioned at the system stop focuses the modulated light output from the first imager on a pixel-by-pixel basis onto the corresponding pixels of the second imager.
