An optoelectronic sensor () for detecting objects comprises a light transmitter () for transmitting a light beam (), a rotatable deflection unit () for periodically deflecting the light beam (), an angle measuring unit () for determining an angular position of the deflection unit (), a light receiver () for generating a reception signal from a reflected light beam (), wherein the angle measuring unit () comprises an image sensor () moving with the deflection unit and arranged in the direction of a stationary part () of the sensor (), or a stationary image sensor () arranged in the direction of the deflection unit (), further comprising a computing unit () to determine a relative movement of the deflection unit () with respect to the sensor () from a signal of the image sensor ().

Optoelectronic detection of objects by measurement of angular position to determine relative movement of a deflection unit

An optoelectronic sensor (), in particular a laser scanner, is provided having a light transmitter () for transmitting a scanning beam () into a monitored zone (); having a light receiver () for generating a received signal from the scanning beam () remitted by objects in the monitored zone (); having a movable deflection unit () for a periodical deflection of the scanning beam () in order to scan the monitored zone () in the course of the movement; having an evaluation unit () that is configured to recognize whether there are objects in at least one detection field within the monitored zone () with reference to the received signal; and having a projector () for visualizing information of the sensor () in the monitored zone (). In this respect, the projector () is configured to visualize the detection field.
