LASER TRANSCEIVING MODULE AND LIDAR SYSTEM

摘要

Provided are a laser transceiving module (20) and a LIDAR system (30). The laser transceiving module (20) comprises: an emitting module (21) adapted to emit laser light beams; a transmission module (22) adapted to transmit the laser light beams to three dimensional space, and receive and transmit echo signals formed by the laser light beam being reflected by obstacles in the three dimensional space; and a probing module (23) adapted to probe the echo signals of the laser light beams transmitted by the transmission module (22); the emitting module (21) and the probing module (23) are arranged on the same side of the transmission module (22), and there is a preset distance between the emitting module (21) and the probing module (23); the transmission module (22) comprises: a first optical assembly (221), the first optical assembly (221) being adapted to collimate the laser light beams emitted by the emitting module (21) and converge the echo signals formed by the laser light beams being reflected by obstacles in the three dimensional space received by the transmission module (22); and a light deflection apparatus (222), the light deflection apparatus (222) being adapted to change the transmission direction of the laser light beams collimated by the first optical assembly (221).
