Abstract

An optoelectronic sensor for the detection and distance determination of objects in a monitoring area is provided having a light transmitter for transmitting a plurality of light pulses, a rotatable deflecting unit, an angle detector, a light receiver, and an evaluation unit which is configured to collect a plurality of reception pulses in a time histogram to determine the light time of flight from the sensor to an object. The evaluation unit is configured to select a respective group of reception pulses that is collected in a histogram based on the angular position signal and to assign the measured value for the object distance determined from the histogram of the group to a detection angle identified by the angular position signal.
