A device for determining a position of an object is provided. The device includes at least one first emitter configured to emit a first transmission light signal that travels from the device to the object, and at least one detector that is configured to detect a reception light signal that travels from the object to the detector. The detector includes at least one pixel matrix that includes at least one pixel. The device includes at least one passive polarization adaptation unit configured to control a polarization of the reception light signal as a function of an ambient light signal. A method for determining a position of at least one object with the aid of such a device is also described, in which the measuring-control element measures a first signal-to-noise ratio at a first measuring point in time, and a second signal-to-noise ratio at a second measuring point in time.

Device and method for determining a position of at least one object

An optical sensor includes first and second light detectors, an optical path, and an evaluation unit. The first light detector detects light in the infrared wavelength range. A light sensitivity of the CCD sensors of the first and second light detectors differ from one another with regard to a predefined wavelength range. The first and second light detectors include pixels in columns and situated next to one another so that a first longitudinal side of the first light detector adjoins a first longitudinal side of the second light detector, and the first and second light detectors receive light via the optical path. The first and second light detectors generate first and second measuring signals, respectively, from electrical charges. The evaluation unit receives the first measuring signals at a first sampling frequency and the second measuring signals at a second sampling frequency, and combines these to form an output signal.
