CATADIOPTRIC PROJECTOR, CATADIOPTRIC PROJECTION SYSTEM AND PROCESS ABSTRACT OF THE DISCLOSURE Catadioptric area-of-interest display projectors produce displays having resolution of substantially less than 10 arc minutes per line over a wide field of view. Such projectors include an external entrance pupil for receiving images of substantially collimated light, and optics for conveying such light onto and through an opening in the surface of an aspheric mirror, and then through an opening in a spherical mirror so that light emerging from the opening in the spherical mirror is displayed on a curved screen surface with such high resolution. A projector system includes this projector and a mirror for steering collimated light from the entrance pupil of the projector 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.
