A device and a method for deflecting a light beam to scan a solid angle range. The device includes: a deflection device having an adjustable micromirror, which is configured to periodically deflect a light beam in accordance with an actuating signal, in order to periodically scan a solid angle range, using the micromirror; a control device to receive a control signal that indicates a currently preferred solid angle in the solid angle range to be scanned, and to generate the actuating signal based on the received control signal; and the control device is configured to generate the actuating signal so that a maximum of a location probability density of the periodically deflected light beam is situated at the solid angle.
