Color illumination system for spatial light modulators using multiple double telecentric relays

摘要

The projector (10) has base condenser relay lens (80) for magnifying uniform illumination field and double-telecentric reducing relay lenses (82) for imaging and directing colored light towards respective spatial light modulators (30) for forming modulated light beams. A dichroic combiner (26) combines modulated light beams to form polychromatic modulated light image for projection by projection lens (32). An independent claim is also included for multicolor image projection method.
