Optical reflecting system
First Claim
Patent Images
1. A reflection system comprising:
- a light emitting projecting means from which intelligible images are projected;
said projecting means having a known focal length;
a receiving surface;
said receiving surface having a known maximum height and width;
said receiving surface further being positioned at a known elevation with respect to said projecting means;
an intermediate curved reflector positioned to receive beams from said projecting means and reflect said beams distortion-free against said receiving surface;
the projection axis of said beams as emitted from said projection means being substantially perpendicular to the plane in which said receiving surface lies;
said reflector having a surface curvature defined by a plurality of incremental arcs, the dimensions and angular disposition of which are successively determinable from each preceding incremental arc;
a central incremental arc having dimensions and angular disposition having been determined from said focal length, said maximum height, said maximum width and said elevation, from which the first of said successive determinations is determinable; and
,said plurality of incremental arcs having dimensions and angular disposition which are proportional to the dimensions and angular disposition of each said preceding incremental arc and the number of all said preceding incremental arc.

Abstract
A reflecting system utilizing a uniquely designed external mirror of specified shape to project and reflect light beams, distortion-free to the eye, from a light source to a receiving surface. The light source is uniquely positioned in relation to the mirror and supplemental mirrors may also be utilized to afford flexibility in the positioning of the elements. A uniquely designed reflector is constructed of a plurality of points specifically determined by an iterative method of solution utilizing as critical variables the size of the viewing surface, the distance from the light source to the reflector and the distance from the reflector to the receiving surface.
