Problems solved by technology

[0004] However, the above-mentioned mechanical rotary laser radar has many disadvantages: the slip ring connecting the rotating part and the fixed part is easy to wear, which affects the service life of the entire device; the rotating part occupies a large volume, and it is difficult to further reduce the volume in future applications. Miniaturization; multi-line (such as 32-line, 64-line) lidar transmitter modules and receiver modules are set in pairs, which requires high angle settings and is difficult to manufacture, which is not conducive to mass production and is expensive

Embodiment 1

[0024] Such as figure 1 As shown, the solid-state laser radar includes a transmitting system 100, a receiving system 200, and an optical assembly 300 corresponding to each other. The transmitting system 100 and the receiving system 200 are arranged side by side. The transmitting system 100 is used to emit laser light, and the optical assembly 300 is used to direct the laser light to the target. , the receiving system 200 is used to receive the reflected light reflected by the target; after the transmitting system 100 emits laser light, the laser light is directed to the target through the optical assembly 300, and the reflected light reflected by the target is received by the receiving system 200 to complete the entire detection process of the lidar.

[0025] Also includes a mounting plate 400, the transmitting system 100, the receiving system 200 and the optical assembly 300 are all arranged on the mounting plate 400, the transmitting system 100 and the receiving system 200 ar...

Abstract

The invention discloses a solid-state laser radar. The solid-state laser radar comprises a transmitting system, a receiving system and an optical assembly which correspond to one another, wherein thetransmitting system and the receiving system are arranged side by side; the transmitting system is used for transmitting laser light; the optical assembly is used for emitting the laser light to a target; and the receiving system is used for receiving reflected light reflected by the target. According to the solid-state laser radar, the environment can be detected and scanned, the requirements ofaccurate detection and good receiving effect can be met, and the solid-state laser radar also has the characteristics of small size, convenience in mounting, adjusting and calibrating, simplicity in use and mounting and the like.

Description

technical field [0001] The invention relates to the technical field of laser detection, in particular to a solid-state laser radar. Background technique [0002] Lidar is a radar system that emits laser beams to detect the target's position, speed and other characteristic quantities. Its working principle is to first emit a detection laser beam to the target, then the receiver receives the signal reflected from the target, and finally the laser radar will reflect the signal. Compared with the transmitted signal, the relevant information of the target can be obtained after proper processing, such as target distance, azimuth, height, speed, attitude, and even shape and other parameters. [0003] Due to the inherent advantages of lidar for environmental perception, it has become the main sensor for autonomous driving technology to detect the environment. At present, the laser radar mainly adopts the mechanical rotation type: the rotating part drives the transmitting module and...
