Abstract: A sensor (10) is provided for detecting an object (20) in a monitored zone (18), having at least one sensor element (36) for detecting a sensor signal; having a switch output (30) for outputting a binary object determination signal; and having an evaluation unit (28) that is configured to generate the object determination signal from the sensor signal in dependence on the detected object (20) and to determine, in a teaching phase, a switching point that determines the association between the sensor signal and the object determination signal. The evaluation unit (28) is further configured to detect a respective sensor signal for a plurality of detection situations in the teaching phase, with the associated object determination signal being predefined for the respective detection situation and with the switching point being derived therefrom.

Abstract: An optoelectronic sensor for measuring a distance comprises a light transmitter (20) for transmitting a sequence of individual light pulses (22) and a light receiver (26) for receiving the individual light pulses (24). An individual time of flight measuring unit (28) determines a sequence of individual times of flight of the individual light pulses (22, 24) as the duration between a transmission point in time and its reception point in time. An evaluation unit (30, 32) accumulates individual times of flight and determines a common measurement value for the distance from the accumulated individual times of flight. The evaluation unit (30) comprises a filter (36) for accumulating an individual time of flight only if it coincides, within a time window, with a preceding individual time of flight.

Abstract: An optoelectronic sensor for detecting an object in a monitored zone is provided that has a light transmitter and a transmission optics associated with the light transmitter in a transmission path for transmitting a light beam and a light receiver and a reception optics associated with the light receiver and offset from the transmission optics by a spacing in a reception path for receiving a light beam remitted by the object and for generating a received light spot on the light receiver, as well a control and evaluation unit that is configured to evaluate a received signal of the light receiver. The reception optics has at least one optical metaelement having a metasurface and/or a metamaterial and is configured such that a displacement of the received light spot on the light receiver in a near zone of the sensor dependent on a distance of the object from the sensor is no larger than a full width at half maximum of the received light spot.

Abstract: An optoelectronic sensor (10) is provided that has a light transmitter (12) for transmitting light (16) into a monitored zone (18); a light receiver (26) having a first plurality of light reception elements (28) for receiving the light (22) reflected or remitted at objects (20) in the monitored zone (20); and a switching signal unit (32) for generating a switching signal from the reception signals of the light reception elements (28). In this respect, a light distribution measurement unit (36) is provided for generating a light distribution signal spatially resolved over the light reception elements (28) from the reception signals of the light reception elements (28) in parallel with the generation of the switching signal.

Abstract: The invention relates to a method of detecting an object in which pulses of transmitted light are repeatedly transmitted into a transmission zone by means of a light source; reception light received from the detection zone is detected by means of a detection apparatus which has a plurality of detectors; and an evaluation zone is defined which comprises a plurality of detectors and within which reception light is incident onto the detectors. The method is characterized in that a plurality of part regions are fixed within the evaluation zone; the part regions are at least partly successively evaluated while using a plurality of consecutive pulses of transmitted light; and the evaluations of the part regions are combined to determine the presence of an object in the detection zone.
