摘要
A fundamental concept of the invention consists thus in the fact that temporally variable reference and object light bundles are generated for object detection, the bundles are superimposed at a light receiver and detected beam by beam and the penetration of the object by selected beams is determined in response to the temporal variability of the superimposed beams.
