Verfahren zum Optischen Abtasten einer Szene

摘要

The invention relates to a method for optically scanning a scene (B) during which the light beam (LS) is diverted inside the prism (PS) by total reflection on a lateral wall of the prism toward the scene and is preferably projected onto the scene via a lens device (OS). The angle of reflection of the light beam is varied by rotating the prism thereby moving the light beam over the scene to be scanned.
