ABSTRACT:
A color management system for use with projection displays includes, for example, two or more analyzers positioned to receive light beams as they are emitted from the panels of a color management system. The analyzers are positioned to receive the light beams directly from the image assimilators before the light has passed through another optical element such as a light combiner. The analyzers are configured for producing filtered light outputs with improved contrast relative to the incoming light beams. By positioning the analyzers to receive the light beams directly from the image assimilators, i.e., prior to passage through other optical elements, the analyzers are able to remove substantially all of the noise before it has become indistinguishable, on the basis of polarization, from the light that comprises the desirable image. Accordingly, this embodiment produces images having dramatically improved levels of contrast relative to prior art systems.
