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) for detecting an object in a monitoring area (20), the sensor (10) having at least one light transmitter (22) for transmitting a plurality of mutually separated light beams (26), a light receiver (34) with a plurality of light receiving elements (34a) for generating a respective reception signal from the remitted light beams (30) remitted by the objects, a receiving optics (32) arranged in front of the light receiver (34) and an evaluation unit (46) for obtaining information about the object from the reception signals, wherein at least some of the light receiving elements (34a) have a mutual offset in a direction perpendicular to their receiving surface.
