Problems solved by technology

[0005] However, in the above-mentioned structure, multi-line lidar is realized by stacking multiple substrates, so when the number of lines of lidar reaches 64 or even 128 lines, the size of the transmitting module will become larger, and because it is necessary to set a side for each The laser-emitting substrates are ray-corrected separately, so it takes a long time to calibrate all the substrates, which slows down the production speed of LiDAR and increases the manufacturing cost

Abstract

The invention discloses a laser emission module and a laser radar with the same. A laser emission module according to an embodiment of the invention comprises a substrate, a support portion arranged on the substrate and having a metal pattern formed on a surface thereof, and a light-emitting part arranged on the support portion and comprising a plurality of lasers capable of emitting laser light,and electrically connected to the substrate through the metal pattern.

Description

technical field [0001] The invention relates to the field of optics, in particular to a laser radar and a transmitting module of the laser radar. Background technique [0002] In the field of autonomous driving, autonomous vehicles can detect surrounding objects with the help of devices such as Lidar (LIDAR). The laser radar can emit a laser beam to the surrounding three-dimensional space as a detection signal, and make the laser beam irradiate the objects in the surrounding space and then be reflected to become an echo signal and return. The laser radar combines the received echo signal with the emitted detection signal Comparisons are made to obtain relevant information about surrounding objects such as distance, speed, etc. [0003] The lidar as mentioned above includes a transmitting module and a receiving module. The transmitting module generates and emits a laser beam, and the laser beam that hits the surrounding objects and reflects back is received by the receiving...
