LASER SCANNER FOR A LIDAR SYSTEM AND METHOD FOR OPERATING A LASER SCANNER

摘要

The present invention relates to a laser scanner (100) for a LIDAR system that scans in a scanning direction. The laser scanner (100) has a laser source (102) which is designed to emit multiple individual light beams (108, 110, 112) into a plurality of angular ranges (114, 116, 118) arranged adjacent to one another transversely to the scanning direction. A receiving optical unit (104) of the laser scanner (100) is designed to concentrate reflected portions (120) of the light beams emitted (108, 110, 112) onto illumination areas (122, 124, 126) of a sensor plane of the laser scanner (100), which illumination areas are arranged adjacent to one another transversely to the scanning direction. Multiple sensor pixels of the laser scanner (100) are arranged adjacent to one another transversely to the scanning direction in the sensor plane. The laser scanner (100) is characterised in that the sensor pixels are arranged opposite the illumination areas (122, 124, 126) in an offset manner transversely to the scanning direction. An electronic control system (128) of the laser scanner (100) is designed to control the laser source (102) such that a plurality of light beams (108, 110, 112) are emitted at different times such that the reflected portion (120) of no more than one of the light beams (108, 110, 112) is incident upon one sensor pixel at the same time.
