Abstract: The present disclosure provides a driving assembly, a LiDAR, and a carrier system. The driving assembly comprises: a shaft comprising a first end and a second end; a first bearing sleeved on an outer side of the shaft and located close to the first end; a second bearing sleeved on the outer side of the shaft and located close to the second end; a stator sleeved on the outer side of the shaft and located between the first bearing and the second bearing; and a rotor assembly fixedly connected to an outer ring of the first bearing and an outer ring of the second bearing and arranged corresponding to the stator, the rotor assembly being configured to be connected to the optical assembly. The spatial arrangement of the driving assembly of the LiDAR improves the stability of the LiDAR during rotation, and reduces the wear of parts and components.

Abstract: The present disclosure provides a transmitter module, a transceiver module for a LiDAR, a LiDAR, and a system. The transmitter module includes a laser emitter, an optical splitter, and a collimation assembly. The laser emitter is configured to emit a laser beam. The optical splitter is located in an outgoing path of the laser beam and is configured to receive the laser beam and split the laser beam into a plurality of split beams. The collimation assembly is located in outgoing paths of the split beams and is configured to receive the split beams and collimate the split beams into collimated beams. This enables the LiDAR to implement multi-line scanning and detection at low cost.
