Simulation display system
First Claim
1. An apparatus for presenting a panoramic scene about a viewing station comprising:
- plural projectors, each projector providing light representative of a given portion of said panoramic scene;
a reflector for each projector that provides an indirect optical path for the propagation of projected light;
an intermediate rear-projection screen receiving the projected light from the plural projectors via the associated reflectors and providing a continuous panoramic object scene in accordance with the projected light received; and
a reflector that forms an enlarged virtual image of said continuous panoramic object scene, said reflector directing the light rays of said continuous panoramic object scene such that said enlarged virtual image appears to be located at a distance from the viewing station substantially greater than that of the direct optical path.

Abstract
A compact display system simulates a panoramic view to an observer located at a central viewing station. A toric mirror, comprising a compressed portion of a sphere, has a concave reflective surface disposed in surrounding relation to the given viewing station while a spherical rear projection screen which receives projected image light on its inner surface presents a panoramic image to the toric mirror from its outer surface. A plurality of projectors are disposed tangentially above the upper periphery of the rear projection screen and project associated portions of the light image onto the inside of the screen via fold mirrors. Each projector includes a high intensity CRT and a color shutter.

8. An apparatus for presenting a panoramic view, said apparatus having a vertical central axis, said apparatus comprising:
-
a toric mirror having a cross section of an arc of a circle in the vertical plane of said apparatus'"'"' central axis, the radius of said circle is greater than half the diameter of said toric mirror; a rear projection screen for receiving projected image light upon its inner surface and presenting a panoramic object image to the toric mirror from its outer surface, said rear projection screen comprising a segment of a sphere having a radius of curvature originating at said central axis; and a plurality of projectors that provide said projected image light, each projector providing image light for an associated portion of said panoramic object image. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)
