ABSTRACT:
Selective light-transmitting filters for use with catadioptic area-of-interest display projectors and projection system provide complementary filters for two or more persons. One of the complementary filters permits all radiance at one predetermined, desired wavelength to be transmitted while rejecting or absorbing all others. The complementary filter for a second viewer transmits substantially all radiance at a second predetermined desired wavelength and absorbs or reflects all others, thus permitting each viewer to see only predetermined, desired displays or parts of a display that are projected simultaneously within the system.
