The invention relates to an optical sensor device (3) for a motor vehicle (1), for the two-dimensional scanning of an area (4) surrounding the motor vehicle (1), said sensor device comprising a transmitter device (5) which has a light source (7) for emitting a light beam (8), and a deflecting device (9) for deflecting the light beam (8) in a first direction (10) about a respective first deflection step angle (21) and/or in a second direction (11) about a respective second deflection step angle (13) in specified scanning steps (A1, A2, A3, B1, B2, B3, B4). The optical sensor device further comprises a receiver device (6) for receiving the light beam (8', 8") reflected in the surrounding area (4). The receiver device (6) has at least two receiver elements (12), and for at least one of the directions (10, 11) each receiver element (12) is assigned at least two scanning steps (A1, A2, A3, B1, B2, B3, B4) for detecting the light beam (8, 8', 8") transmitted in the respective scanning steps (A1, A2, A3, B1, B2, B3, B4) and reflected in the surrounding area (4). The receiver device (6) has an optical imaging device (15) for enlarging detection regions (14) of the at least two receiver elements (12) in the direction (10, 11) with the at least two assigned scanning steps (A1, A2, A3, B1, B2, B3, B4). The invention also relates to a motor vehicle (1) and to a method. |
