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.

Abstract: An optical module includes a housing, and a main circuit board, an optical transmitting assembly, an optical receiving assembly, and an electrical connector that are disposed inside the housing. The optical transmitting assembly includes at least two sets of lasers, a transmitting-end optical assembly, and a transmitting-end optical fiber receptacle. The optical receiving assembly includes at least two sets of photoelectric detectors, a receiving-end optical assembly, and a receiving-end optical fiber receptacle. The electrical connector electrically connects the optical transmitting assembly and the optical receiving assembly to the main circuit board.

Abstract: An optical module includes a housing extending in a lengthwise direction, as well as a main circuit board and an optical receiver assembly disposed in the housing. A plane on which the main circuit board is located is parallel to the lengthwise direction of the housing. The optical receiver assembly includes a receiver-end fiber optic port, at least two sets of receiver-end photoelectronic chips arranged side by side along the lengthwise direction, and a receiver-end optical component set including an optical demultiplexer and at least two coupling components located at an exit end of the optical demultiplexer. The at least two coupling components are arranged side by side along the lengthwise direction, and have different distances, respectively, to the plane on which the main circuit board is located along a first direction perpendicular to the plane on which the main circuit board is located.
