Abstract:
1. A method of controlling the physical distribution of reflected light from a reflector comprising: forming a desired surface specularity on a tool made of hardened steel by grinding or polishing and/or buffing, permanently replicating said desired surface to a mating surface of said reflector by transferring the solid angle reflections of the tool by applying a short pulse of sufficient pressure increase in forming process by relatively moving an inner surface of the reflector intimately against the tool overcoming any residual forming stresses, testing the desired specularity by a laser at each required mating area by displaying the degree of reflectance specularity geometrically in solid angle patterns, such that the incident laser beam reflecting from the reflector projects a three dimensional beam collected by a detector means and displaying the actual solid angle reflection properties of the surface over a range of totally specular to totally diffuse and further by controlling real or proposed distribution of diffuse reflected light via a vector representation provided as a math model for ray tracing and recovery of portions of diffuse reflected light.
