Claim 14:
15. A method of detecting objects in a monitored zone in which at least one scanning beam is transmitted, comprising:
periodically deflecting the at least one scanning beam in a first direction by means of a movable first deflection unit;
generating a received signal from the at least one scanning beam reflected remitted by objects in the monitored zone;
evaluating the received signal to determine a distance from an object scanned by the at least one scanning beam by a time of flight process; and
additionally deflecting the at least one scanning beam in the first direction and/or in a second direction transverse to the first direction without a movement or at most with micromechanically moved elements,
wherein the at least one scanning beam selectively leads and/or trails in the first direction with respect to an angular rate defined by the periodic deflection of the at least one scanning beam.
