发明名称 OPTICAL ILLUMINATION AND DISTORTION COMPENSATOR
摘要 Method and apparatus for a visual display system in a vehicle simulator to compensate for distortion and to maximize illumination in a projected image substantially at the same time. When a spherical mirror (11) is interposed between a curved rear-projection screen (12) and a viewing position (10), certain distortions are developed which detract from realism. Such distortions are compensated for by reflecting the image off a curved folding mirror (13) positioned so that its major axis (CL-2) is substantially perpendicular to the major axis (CL-1) of the curved rear-projection screen (12). In accordance with the invention, when such compensation is achieved, the illumination of the projected image will be to substantially its brightest.
