OPTICAL OBJECT-DETECTION DEVICE HAVING A MEMS AND MOTOR VEHICLE HAVING SUCH A DETECTION DEVICE

摘要

The invention relates to an optical object-detection device (1) for a motor vehicle (26), comprising a transmitting unit (2) for emitting a transmitted light beam (5), a receiving unit (3) for receiving a received light beam (8), and an electronic evaluating device for detecting an object external to the vehicle in an environment of the motor vehicle (26) in dependence on the received light beam (8). The transmitting unit (2) comprises a transmitter (4) for producing the transmitted light beam (5), a controllable micromirror (11), by means of which the transmitted light beam (5) can be pivoted at least in a first pivoting direction (10), and a transmitting lens (17) arranged after the micromirror (11) in the transmitted beam path. At least along the first pivoting direction (10), the transmitted lens (17) is designed as a concave-convex lens having a concavely curved surface (18) facing the micromirror (11) and a convexly curved surface (19).
