Abstract: A LiDAR and a LiDAR scanning method are provided. The LiDAR includes a transceiving module, a control unit, a galvanometer, and a motor. The galvanometer is a one-dimensional galvanometer. The galvanometer is driven by the control signal to perform vertical scanning, and the galvanometer performs horizontal scanning as the motor rotates, so that the LiDAR performs scanning in the horizontal direction and the vertical direction. Through the present application, a scanning range of the LiDAR can be enlarged, a structure of the LiDAR can be simplified, and resolution and precision of the LiDAR can be improved.

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: Embodiments of a laser transceiving module and a LiDAR are disclosed. The laser transceiving module includes a housing; an emitting module configured to emit emergent laser signals; a laser splitting module; and a receiving module. The emergent laser signals emit, through the laser splitting module, outwards and are reflected by a target object in a detection region to return reflected laser signals. The laser splitting module is configured to deflect the reflected laser signals. The receiving module is configured to receive the deflected reflected laser signals. The emitting module, the laser splitting module, and the receiving module are fixed at the housing. An extinction structure is arranged between the emitting module and the laser splitting module and is configured to prevent the emergent laser signals that are reflected by the laser splitting module from emitting to the receiving module.

Abstract: A lidar and a lidar adjustment method are provided. The lidar includes at least one transceiver component. The at least one transceiver component includes an emitting assembly, a beam splitting assembly, and a receiving assembly. The emitting assembly is configured to emit an outgoing light signal. The outgoing light signal is emitted, through the beam splitting assembly, towards a detection region and reflected by a target object to form a reflected light signal. The receiving assembly is configured to receive the reflected light signal after being deflected by the beam splitting assembly.
