Abstract

A micromirror scanner and a method for controlling a micromirror scanner. The method includes furnishing a shot pattern which has at least information regarding first control application signals as a function of mirror positions of a displaceable micromechanical mirror of the micromirror scanner, which are designated to control a light source of the scanner; determining a mirror position of the mirror; emitting light beams into a solid angle; measuring light beams reflected at an object in the solid angle to determine a distance between the object and the scanner; determining a nature or position of the object with respect to the scanner as a function of the determined distance and the determined current mirror position; and adapting the shot pattern as a function of the position and/or nature of the object.
