Abstract: This disclosure provides an optical receiving apparatus, including a photodetector and a plurality of beam homogenization units. The photodetector includes a plurality of pixels, each pixel includes a plurality of cells, and the cell is configured to convert a received optical signal into an electrical signal. Each beam homogenization unit corresponds to at least one pixel of the photodetector, and is configured to diffuse a received incident light beam to a plurality of cells included in the corresponding at least one pixel. The optical receiving apparatus may be applied in a light detection and ranging system. The apparatus increases dynamic ranges of the detector and the light detection and ranging system, and improves detection efficiency.
