Abstract

The invention provides a single-line laser radar which comprises a first beam expanding collimating lens and a second beam expanding collimating lens which are adjacently arranged. A laser detector isarranged at the focal length position of the first beam expanding collimating lens, and a main detection light path of the laser detector coincides with the optical axis of the first beam expanding collimating lens. And a semiconductor laser module is arranged at the focal length position of the second beam expanding collimating lens and deviates from the optical axis of the second beam expandingcollimating lens. The semiconductor laser module integrates a fast-axis compression lens and a slow-axis compression lens and can emit a circular Gaussian beam or a near-circular Gaussian beam through reasonable design. The distance between the main light of the semiconductor laser module and the optical axis of the second beam expanding collimating lens does not exceed the radius of the detection surface of the laser detector.

Description

technical field [0001] The invention relates to the field of laser radar, in particular to a single-line laser radar. Background technique [0002] Lidar is one of the core key sensors to realize the intelligent perception of the surrounding environment. It has the characteristics of high ranging accuracy, long distance, fast response, and strong anti-interference ability. It is more and more widely used in unmanned driving, robots, intelligent security, and environmental protection. monitoring and other fields. At present, the detection distance of single-line lidar is relatively short, and the reliability of measurement still needs to be further improved. In addition, the precise assembly and adjustment of lidar is often time-consuming and inefficient. In order to solve these problems, it is necessary to conduct in-depth research. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a single-line laser radar with...
