INTERFERENCE LIGHT FIELD RECONSTRUCTION USING SPARSELY DISTRIBUTED LIGHT POINTS

摘要

An optical system adapted to reconstruct an interference light field comprising: a spatial light modulator (104) comprising an array of pixels (106) optically aligned to an optical element (108) comprising an array of light point forming elements (112) formed in a first transparent substrate (110), each light point forming element including a light receiving area (114) to receive light from a reference light source (102) and an associated light transmitting area having a light point (120) that emits light out of the light emitting area; at least one mask element (119) and/or refractive element in each light point forming element causing the locations of the light points to be arranged a-periodically; and, the pixels of the spatial light modulator controlling the intensity of the light transmitted to form the interference light field at a predetermined location relative to the optical system.
