Device and method for deflecting a beam of light

A device for deflecting a beam of light, comprising:

• an adjustable deflection device;
• a closed-loop control unit designed to generate an actuating signal by which the deflection device is controlled in a periodic movement for scanning a solid angle region with the aid of a beam of light that the beam of light is deflected by the deflection device;
• and
• a detector device designed to detect an impingement or a missing impingement of the scanning beam of light on the detector device and to generate a measuring signal on the basis of the detection;
• wherein the closed-loop control unit is designed to adapt the actuating signal on the basis of at least the measuring signal.

A method for deflecting a beam of light, the method comprising:

• controlling a deflection device with the aid of a control signal for scanning a solid angle region with the aid of a beam of light, deflected by the deflection device, in a periodic movement;
• detecting an impingement or a missing impingement of the scanning beam of light on a detector device;
• generating a measuring signal based on a result of the detection;
• and
• adapting the actuating signal based on the measuring signal.
