Problems solved by technology

In any case, except in special cases, only a very small light component of the backscattered light scattered back by the object hits the detector unit, which correspondingly limits the detection range
For eye safety reasons, the laser power can only be increased up to certain limit values

Abstract

The invention relates to a LIDAR assembly (1) comprising a plurality of LIDAR systems (10, 20). The first LIDAR system (10) is spaced apart from the second LIDAR system (20). A first laser beam (13) of the first LIDAR system (10) and a second laser beam (23) are synchronized such that said first laser beam (13) and second laser beam (23) are mutually amplifying in a common remote region (50).

Description

technical field [0001] The invention relates to a laser radar assembly, a vehicle and a robot with the laser radar assembly. Background technique [0002] The scanning laser radar system (lidar = light detection and ranging) scans a certain scanning area or spatial area with a pulsed laser beam, and calculates the existence and distance of the object hit by the laser beam. In this case, a lidar system usually has a laser source for generating a laser beam, a scanning device for scanning the emitted laser beam over a certain scanning area, and a detector unit for detecting the backscattered light. There are various alternatives for the scanning device here. For example, the detector unit and the laser may be pivoted together by the scanning device, only the laser pivoted, or beam deflecting elements such as micromirrors or polygons scan the laser beam. [0003] If the laser beam hits the object, the reflected light or the backscattered light is distributed over a wide spati...
