ABSTRACT:
A color management system for use with projection displays includes an image assimilator and an analyzer. The image assimilator comprises a panel that produces a light beam comprising spatial information. The image assimilator also comprises a field lens positioned to receive the light beam and configured to emit a converging light beam whose cross-sectional area decreases with distance from the field lens. In an exemplary embodiment, a plurality of image assimilators and associated analyzers are included, each having a field lens for emitting a converging light beam. The analyzers are configured for producing filtered light outputs with improved contrast relative to the converging light beams. In addition, the converging nature of the field lens emitted light beams enables the size of the analyzers and other downstream components to be minimized. Accordingly, this embodiment produces images having dramatically improved levels of contrast with reduced size relative to prior art systems.
