Abstract
An optical sensor comprises a light transmitter; a light receiver; an evaluation unit; at least one mirror unit that comprises a plurality of micromirror elements having an at least regionally reflective surface and comprising an electrode arrangement connected to the micromirror elements; and a control device that is configured to adjust the mirror unit between at least two different functional states by controlling the electrode arrangement. The mirror unit comprises an at least substantially transparent substrate at which the micromirror elements are arranged. The control device is configured to temporarily set the mirror unit into a transmission state in which the micromirror elements are in an open position and light radiation incident onto the mirror unit moves past the micromirror elements through the transparent substrate.
