摘要： An optical receiver (100) for detection of light from one or more sources (108) comprises an opaque layer (102) disposed on a first surface. An aperture (104) is formed in the opaque layer. An optical detector (106) has a detection region disposed on a second surface. The first and second surfaces are spaced apart from one another such that light passing through the aperture (104) illuminates a corresponding illumination region (110) on the second surface, and is detected by the optical detector (106) In the event that the detection region overlaps the illumination region. Multiple apertures may be formed in the opaque layer, and/or multiple optical detectors may be disposed on the second surface. The optical receiver may thereby enable optical signals originating at different locations to be detected, and distinguished, over a wide field of view.
