Laser scanners for lidar systems, and methods for operating laser scanners

摘要

A laser-scanner for a LIDAR system scanning in a scanning direction, having a laser-source to emit a plurality of individual light-beams into a plurality of angular-ranges which are situated next to one another transversely to the scanning-direction. A receiver-optics of the laser-scanner is configured to concentrate reflected portions of the emitted-light-beams on exposure-regions of a sensor-plane of the laser-scanner that are situated next to one another transversely to the scanning-direction. A plurality of sensor-pixels of the laser-scanner are situated next to one another in the sensor-plane transversely to the scanning-direction. The sensor pixels are situated at an offset vis-a-vis the exposure-regions transversely to the scanning-direction. A control-electronics of the laser-scanner is configured to actuate the laser-source so that a plurality of light-beams is emitted in a time-staggered manner such that no more than the reflected portion of one of the light-beams impinges upon a sensor-pixel at the same time.
