摘要： Catadioptric area-of-interest display projectors (1) produce displays having resolution of substantially less than 10 arc minutes per line over a wide field of view. Such projectors (1) include an external entrance pupil (21) for receiving images of substantially collimated light, and optics (2-17) for conveying such light onto and through an opening (19) in the surface (35) of an aspheric mirror (18), and then through an opening (20) in a spherical mirror (33) so that light emerging from the opening (20) in the spherical mirror (33) is displayed on a curved screen surface with such high resolution. A projector system includes this projector (1) and a mirror for steering collimated light from the entrance pupil (21) of the projector (1) into the projector optics. This system, when placed in a flight simulator at the periphery of a flight simulator dome for projection of such light images onto the inner curved surface of the dome, provides high resolution images to viewers located at the center of the dome.

摘要： 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.
