Abstract
Abstract The system herein includes light optic means which functions as light beam distributor in making available, almost instantly, one or more of a plurality of input light beams at any of a plurality of differently positioned output paths of the system as opposed to the more well known line scan beam deflection systems. The input beams may be from individual laser sources of radiant energy, each providing a different color of light, whereupon light from these sources may be combined and directed along a common output path.

Claim 1
Independent Claim
289 words
Light beam distributor and reflection control means, comprising: (a) at least first and second light admitting surfaces: (b) at least first and second sources of light; (c) means for directing light from said first and second sources along corresponding first and second input paths and, respectively, toward said first and second admitting surfaces and thereupon along a primary optical path within said distributor while undergoing a series of light reflections therein so as to establish an availability of light from said first and second sources at a plurality of predetermined light output positions of said distributor for an optically controlled redirecting of light along a selected one of a plurality of secondary paths stemming from said output positions; (d) said means for directing the light along said primary path including an array of light reflecting interfaces of first and second light conducting media presenting, respectively, first and second indices of refraction, each of said interfaces presenting a length dimension and each angularly oriented so as to establish an optical relationship one with respect to the other, with respect to said input paths, and with respect to said secondary paths, said array of interfaces providing a series of 360° primary optical paths for said light, each said 360° path displaced one with respect to the other in a side-by-side relationship in the direction of said length dimension; (e) said output positions extended along said length dimension coincident with a predetermined one of said interfaces of first and second light conducting media of said array of interfaces; (f) light reflection control means positioned along said length dimension for effecting, selectively, a redirecting of light of said first and second sources along a secondary path stemming from a corresponding output position thereof.
