摘要:
A light diffuser panel for coupling to an optical element, includes a plurality of first type layers of a first type of material with a refractive index n1, and a plurality of second type layers of a second type of material with a different refractive index n2, wherein each of the first type layers and each of the second type layers are arranged to form a plurality of interface surfaces between alternating first type layers and second type layers, tilted at a plurality of angles with tilt axes that are parallel to a plane of the light diffuser panel, such that visible light from the optical element is transmitted through the light diffuser panel and the interface surfaces, and a portion of the visible light from the optical element is reflected out of the light diffuser panel at each of the interface surfaces.
