Abstract:
The invention relates to a method for controlling a light scanner (7) in a headlight for vehicles, wherein the laser beam of at least one modulated laser light source (1) is directed in a scanning manner, by way of the light scanner, onto a light conversion means (8) so as to generate a light image (11) thereon, which is projected via an imaging system (12) as a light image (11′) onto the roadway, a micromirror (10) of the light scanner is pivoted according to defined characteristic control curves in at least one coordinate direction, the desired light image (11) is divided into a pixel set having n rows and/or m columns, the horizontal and/or vertical characteristic control curves for the micromirror (10) are adapted to at least one selected row and/or column in terms of the required optical power of the pixels, and the adapted horizontal and/or vertical characteristic control curves are used to control the micromirror.
