Abstract: An apparatus in the field of optics technology, can include a reflector, a reflector substrate, and an extinction component. The reflector can be mounted on the reflector substrate. The extinction component can be arranged on a front surface of the reflector substrate. The reflector can be configured to reflect incident light signals. The extinction component can be configured to reduce the scattered light produced by the incident light signal on the reflector substrate. An optical scanning device (for example, lidar) having such features may greatly reduce the scattered light inside the lidar, reduce the detection blind area caused by the stray light, and greatly improve the receiving and detecting capabilities of the lidar.

Abstract: This application pertains to the technical field of LiDAR, and discloses a receiving optical system, a laser receiving module, a LiDAR, and an optical adjustment method. The receiving optical system includes an optical receiving module and a first cylindrical lens. The optical receiving module is configured to receive a reflected laser and focus the received reflected laser. The first cylindrical lens is configured to receive the focused reflected laser and adjust the reflected laser in a first direction. Therefore, the receiving optical system can better perform matching on the photosensitive surface of the receiving sensor, and the energy receiving efficiency of the system is relatively high.
