OPTICAL SYSTEM GENERATING A STRUCTURED LIGHT FIELD FROM AN ARRAY OF LIGHT SOURCES BY MEAND OF A REFRACTING OR REFLECTING LIGHT STRUCTURING ELEMENT

摘要

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.
