摘要： An optical relay comprises a light-transmissive substrate having a plurality of diffractive optical elements, where at least one diffractive optical element is characterized by nonuniform diffraction efficiency. The substrate and diffractive optical elements are designed and constructed to relay at least a portion of a light beam emanating from an object to at least one predetermined eye-box in a manner such that for each point of the object, there is a set of parallel outgoing light rays originating from the point and arriving to the eye-box. The color difference between any two parallel light rays of the set is less than 50 ΔE* units.

摘要： An optical relay device, for relaying polychromatic light is disclosed. The device comprises: an input optical element formed in a planar substrate for receiving and redirecting the light for propagation of the light in a lateral direction within the substrate; and an output optical element formed in the substrate for receiving light propagating within the substrate and coupling the light out of the substrate. The device further comprises a reflector assembly at least partially coating opposite surfaces of the substrate for substantially reflecting light rays impinging on the reflector assembly at an angle within a first angular range, and substantially transmitting light rays of the polychromatic light impinging on the reflector assembly at an angle within a second angular range. In some embodiments of the present invention the input optical element and the output optical element are diffraction gratings having a periodic profile shaped such that at least one portion of the light is dominantly coupled into a diffraction order m satisfying |m| > 1.
