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.
