LIDAR sensor for the optical detection of a field of view and method for controlling a LIDAR sensor

摘要

LIDAR sensor (100) for optically detecting a field of view, comprising a transmission unit with at least one light source (101, 101-1, 101-2) for generating and outputting primary light in a first angular range (111) of the field of view; a deflection unit (105) rotatable and / or pivotable about an axis of rotation (106) for deflecting primary light incident on the deflection unit (105) into a second angular range (505) of the field of view; and a receiving unit (110) with at least one detector unit (204) for receiving secondary light which has been reflected and / or scattered in the field of view by an object; wherein the first angular range (111) is extended in a plane arranged parallel to the axis of rotation (106) of the deflection unit (105); and wherein the transmission unit is designed to transmit the primary light as a first bundle of transmitted rays (102-1) with two edge rays (103-1, 103-2) and as at least one second bundle of transmitted rays (102-2) with two edge rays (1041, 104- 2) to output in at least two sub-areas (111-1, 111-2) of the first angular range (111); and wherein the transmission unit is further designed to output the first transmission beam (102-1) in such a way that the first edge beam (103 1) of the first transmission beam (102 1) hits a first edge region (112-1) of a surface of the deflection unit (105 ) occurs; and to output at least one second bundle of transmitted rays (102-2) in such a way that the first marginal ray (104 1) of this second bundle of transmitted rays (102-2) hits a second edge region (112-2) of the surface of the deflection unit (105) opposite the first edge region. hits.
