Abstract: An optoelectronic sensor (10) for detecting an object in a monitored zone (20) that has at least one light transmitter (22) for transmitting a plurality of mutually separated transmitted light beams (26a-d); a plurality of light receivers (34a-d) that are each associated with one of the transmitted light beams (26a-d) for generating a received signal from the associated light beam (26, 30) remitted at the object; and an evaluation unit (46) that is configured to acquire information on the object at the respective point of incidence of the transmitted light beam (26a-d) from the received signal of the light receiver (34a-d) that is associated with the transmitted light beam (26a-d) and to additionally consider at least one received signal of a light receiver (34a-b) that is not associated with the transmitted light beam (26a-d) on the acquiring of information on the object at the point of incidence of at least one transmitted light beam (26a-d).

Abstract: An optoelectronic sensor (10) is provided for the detection of objects in a monitored zone (20) that has a light transmitter (12) for transmitting transmitted light (16), a laser scanner (26) for generating a received signal from received light (22) from the monitored zone (20), a movable deflection unit (18) for the periodic deflection of the transmitted light (16) and of the received light (22), a control and evaluation unit (32) for the detection of information on objects in the monitored zone (20) using the received signal, and an optical deflection element (18, 40), in the optical path of the received light (22), In this respect, the deflection element (18, 40) has temperature dependent beam shaping properties.

Abstract: An optoelectronic sensor for detecting an object in a monitored zone is provided having a light transmitter for transmitting transmitted light of a wavelength range; having a light receiver for producing a received signal from the transmitted light remitted at the object; having a reception optics that is arranged upstream of the light receiver and that has an optical filter adapted to the wavelength range for suppressing extraneous light; and having a control and evaluation unit that is configured to produce a piece of object information from the received signal, An adjustment device for changing the angle of incidence of the remitted transmitted light on the optical filter is provided here.
