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

摘要

An optical object sensing device for a motor vehicle, having an emitter unit for emitting an emission light beam and having a receiver unit for receiving a reception light beam, and having an electronic evaluation device for detecting an object external to the vehicle in a vicinity of the motor vehicle as a function of the reception light beam. The emitter unit includes an emitter for generating the emission light beam, a controllable micromirror by which the emission light beam can be panned at least in a first panning direction, and an emission lens arranged behind the micromirror in the emission beam path, where at least along the first panning direction, the emission lens is configured as a concave-convex lens with a concavely curved surface, which faces towards the micromirror, and with a convexly curved surface.
