ABSTRACT:
An optical concentrator increases the power density from diffuse optical energy remitted by an optically diffusing surface by at least partially recollimating the diffuse optical energy. The concentrator includes an optical diffuser element illuminated at a first point by optical input energy and remitting incident optical energy. A reflective element has a reflective surface with a concentration point located at the first point and the reflective surface reflects diffuse optical energy incident on it from the diffuser element. At least one aperture is provided for the transmission of an output beam formed by a portion of the diffuse optical energy from at least the diffuser element.
