Abstract: A LiDAR includes a flat platform and a detection device rotatably fixed on the flat platform. The detection device includes: a lens tube, a light beam emitting device, an emitting lens assembly, a receiving lens assembly, and a photoelectric processing device. The emitting lens assembly is located on a path of a detection light beam emitted by the light beam emitting device. The receiving lens assembly is located on a path of an echo light beam received by the photoelectric processing device. The lens tube includes an emitting support and a receiving support that are separable and extend in directions parallel to each other, and the emitting lens assembly is located inside the emitting support and the receiving lens assembly is located inside the receiving support, such that an exiting direction of the detection light beam and an incident direction of the echo light beam are parallel to each other.

Abstract: A light detection and ranging (Lidar) system includes: a main shaft, a radar rotor, an upper cartridge plate, a top cover, and a base. The upper cartridge plate is fixedly disposed relative to the radar rotor. The upper cartridge plate is closer to the base than to the top cover in an axial direction of the Lidar system. The main shaft is disposed perpendicular to the base and is located between the upper cartridge plate and the base. The Lidar system can shorten wiring of every module, is convenient to install and maintain, and has an improved mechanical reliability.
