OPTICAL ILLUMINATION AND DISTORTION COMPENSATOR |
摘要 |
This disclosure describes a 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. Where a spherical mirror is interposed between a curved rear-projection screen and a viewing position, certain distortions are developed which detract from realism. Such distortions are compensated for by reflecting the image off a curve folding mirror positioned so that its major axis is substantially perpendicular to the major axis of the curved rear-projection screen. In accordance with the invention, when such compensation is achieved, the illumination of the projected image will be at substantially its brightest. |
