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.

Abstract: A scanning system, a detection system, and a terminal device are provided, and may be applied to fields such as autonomous driving, intelligent driving, assisted driving, or surveying and mapping. The scanning system includes a scanning module and an optical processing module. The optical processing module includes a light isolation component. The light isolation component includes a first flange and/or a second flange. The scanning module includes a scanner that is divided into a first sub-scanner and a second sub-scanner based on the light isolation component. The first flange faces a side of the first sub-scanner, and the second flange faces a side of the second sub-scanner. The first sub-scanner is configured to reflect, to a detection area, detection light from an emitting module, and the second sub-scanner is configured to reflect an echo signal to a receiving module.
