OPTICAL SYSTEM GENERATING A STRUCTURED LIGHT FIELD FROM AN ARRAY OF LIGHT SOURCES BY MEANS OF A REFRACTING OR REFLECTING LIGHT STRUCTURING ELEMENT
First Claim
1. An optical system for the generation of a structured light field to illuminate a scene, comprising an array of light sources and a structuring unit arranged in front of said array of light sources, said structuring unit comprising an array of first optical surfaces having individual orientations, wherein the individual orientations of said optical surfaces of said structuring unit are configured so that individual light beams emanating from said light sources are individually directed into the scene under respective vertical and horizontal angles by refraction and/or reflection at said first optical surfaces.

Abstract
An optical system for the generation of a structured light field comprises an array of light sources and a structuring unit separate from said array of light sources, said structuring unit being refractive or reflective and transforming the output of that array of light sources into a structured light illumination by collimating the light beam of each individual light source and directing each beam into the scene under vertical and horizontal angles that can be arbitrarily chosen by refraction or reflection.
