Classification: CPC G | IPC G

Claim 0:
1. An optoelectronic sensor for detecting objects in a monitored zone, the optoelectronic sensor comprising:
a light transmitter for transmitting at least one scanning beam;
a movable first deflection unit for a periodic deflection of the at least one scanning beam in a first direction;
a light receiver for generating a received signal from the at least one scanning beam reflected by objects in the monitored zone;
a control and evaluation unit that is configured to evaluate the received signal to determine a distance from an object scanned by the at least one scanning beam using a time of flight process; and
a second deflection unit that is configured to additionally deflect 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 control and evaluation unit is further configured to allow the at least one scanning beam to lead and/or trail in the first direction with respect to an angular rate defined by the periodic deflection of the at least one scanning beam.
