Claim 16:
17. A method for detecting objects in a monitored region, comprising the steps of:
transmitting a plurality of light beams through a common transmission optics, wherein each of the light beams is separate from other ones of the light beams, and wherein each of the light beams starts from a respective individual transmission point located at at least one light transmitter;
reflecting the plurality of light beams from the objects;
following passage through a reception optics, a plurality of remitted light beams arriving incident at respective individual reception points located at at least one light receiver in order to produce respectively received signals; and
evaluating the received signals for obtaining of information on the objects,
wherein the transmission points are arranged on a first circular line and/or the reception points are arranged on a second circular line,
wherein the transmission points, the common transmission optics, the reception points, and the common reception optics rotate together about a common axis of rotation to periodically scan the monitored region, and
wherein at least one of the at least one light transmitter and the at least one light receiver form components having basic surfaces, wherein the basic surfaces are at least partly rotated with respect to one another in a plane defined by a corresponding one of the first and/or second circular lines.
