Abstract: A projection and display system for reverse projection of imagery includes an imagery projection system having a lens barrel for projecting images. The imagery projection system extends into a substantially closed, geometric viewing surface, such that the lens barrel is disposed at a predetermined distance from and at a predetermined orientation relative to an interior surface of the geometric viewing surface. The images are projected onto an interior surface of the geometric viewing surface. The images may be defined in vector coordinates or in raster coordinates.

Abstract: A projection system for projecting computergraphic images onto a domed or spherical viewing surface. An intense beam of coherent light is color and intensity modulated and deflected in a pair of cartesian axes prior to being projected through a wide angle lens array. Because the light beam is deflected before entering the wide angle lens array, greater angles of deflection are possible. The images are generated by rapidly changing the deflection of an intense spot of light which is projected onto the viewing surface at a rate above the viewer's flicker rate. This wide angle lens array may include a scan flattening lens array by which the image can be focused onto a spatial image focal plane before it is projected through a wide angle lens.
