Optical sensor

An optical sensor, comprising:

• a first light detector configured to detect light in the infrared wavelength range;
• a second light detector;
• an optical path;
• and
• an evaluation unit;
• wherein each of the first light detector and the second light detector:
• is a CCD sensor, a light sensitivity of the CCD sensor of the first light detector differing from a light sensitivity of the CCD sensor of the second light detector with regard to a predefined wavelength range,
• includes pixels that are arranged in columns and situated next to one another in such a way that a first longitudinal side of the first light detector adjoins a first longitudinal side of the second light detector, and
• is configured to receive light via the optical path;
• wherein the optical sensor, in conjunction with the first light detector, is configured to generate first measuring signals from electrical charges, and in conjunction with the second light detector, is configured to generate second measuring signals from electrical charges;
• and
• wherein the evaluation unit is configured to receive the first measuring signals at a first sampling frequency and the second measuring signals at a second sampling frequency, and to combine together the first measuring signals and the second measuring signals to form an output signal.
