Abstract

The invention provides a packaging process of a multi-transmission-channel laser radar optical coupling system. The packaging process of the multi-transmission-channel laser radar optical coupling system comprises the following steps: a primary assembly step and a packaging step: mounting a plurality of lenses of a lens array and first ends of a plurality of optical fibers of an optical fiber array structure at a plurality of mounting positions of a first fixing structure in a one-to-one correspondence manner, and packaging and fixing the lenses and the first ends of the optical fibers to thefirst fixing structure; a secondary assembly step: mounting second ends of the plurality of optical fibers at a plurality of mounting positions of a second fixing structure in a one-to-one correspondence manner; a secondary packaging step: packaging and fixing the second ends of the optical fibers to the second fixing structure; and a grating array structure fixing step: aligning a plurality of gratings of a grating array structure with the second ends of the plurality of optical fibers one by one and packaging and fixing the gratings and the second ends. According to the invention, the problem that optical fibers of an optical coupling system of a laser radar in the prior art are easy to misplace is solved.

Description

technical field [0001] The present invention relates to the technical field of optical devices, in particular, to a packaging process of a multi-transmission channel laser radar optical coupling system. Background technique [0002] Lidar (Light Detection and Ranging, Lidar) is a radar system that uses laser as an information transmission carrier to detect target-related feature quantities. The working principle of lidar is mainly by emitting laser light, the laser irradiates the sample to be tested and then reflects and carries the information of the sample to be tested to form an echo, and the received echo light signal is processed for data, so as to realize the distance and angle of the sample to be tested. detection and identification. The existing lidar system is mainly composed of laser transmitter, optical coupling system, laser detection system and information processing system. With the rapid development of laser technology and optical fiber technology, the requi...
