METHOD FOR ALIGNING AND/OR POSITIONING A LASER MODULE OF A LASER PROJECTOR, LASER PROJECTOR, AND ALIGNING AND/OR POSITIONING DEVICE

Abstract: a method for aligning and/or positioning a laser module of a laser projector relative to at least one other laser module of the laser projector. a laser beam output by the laser module is scanned by a micromirror over a region which includes a target; another laser beam output by the other laser module is scanned by the same micromirror over another region which includes the same target. a reflection signal of the scanned laser beam and another reflection signal of the other scanned laser beam are detected based on a micromirror operating parameter which is detected or ascertained simultaneously with the respective reflection signals. the alignment and/or position of at least the laser module is adapted.
