Lidar sensor, in particular for motor vehicles, having a light source (12), a movable deflection mirror (18) for producing a scanning beam (32), which scans a monitoring space (36), by deflecting a light beam (14) emitted by the light source (12), and having an optical receiver (42) for detecting light which has been reflected at an object (38) which has been hit by the scanning beam (32) in the monitoring space (36) , characterized in that the light source (12) and the deflection mirror (18) are set up to use the deflected light beam (26) to scan an array (20) of micro-optical elements (22), each of which, when hit by the light beam, widens this light beam to form a divergent beam (28), and in that a light-focusing element (30) is arranged at a distance from the array (20) of micro-optical elements and converts the divergent beam (28) into a beam which forms the scanning beam (32) and the beam diameter of which is greater than that of the deflected beam (26). |
