Abstract: An optoelectronic sensor (10), in particular a laser scanner, is provided having a light transmitter (12) for transmitting a scanning beam (16) into a monitored zone (20); having a light receiver (26) for generating a received signal from the scanning beam (22) remitted by objects in the monitored zone (20); having a movable deflection unit (18) for a periodical deflection of the scanning beam (16, 22) in order to scan the monitored zone (20) in the course of the movement; having an evaluation unit (34) that is configured to recognize whether there are objects in at least one detection field within the monitored zone (20) with reference to the received signal; and having a projector (42) for visualizing information of the sensor (10) in the monitored zone (20). In this respect, the projector (42) is configured to visualize the detection field.

Abstract: A beam splitter arrangement for an optoelectronic sensor, an optoelectronic sensor having such a beam splitter arrangement, and a method of beam splitting in an optoelectronic sensor are provided, wherein the beam splitter arrangement has at least one input for coupling first transmitted light beams having first transmitted light pulses into the beam splitter arrangement. At least one beam splitter splits the first transmitted light beams into a plurality of second transmitted light beams having second transmitted light pulses. The beam splitter arrangement further has a plurality of outputs for decoupling the second transmitted light beams from the beam splitter arrangement, with the number of outputs being greater than the number of inputs. Optical compression paths that compress the second transmitted light pulses such that a second pulse length of the second transmitted light pulses is shorter than a first pulse length of the first transmitted light pulses are arranged downstream of at least one beam splitter.
