Optoelectronic Sensor and Method for the Detection of Object Information

摘要

An optoelectronic sensor (100) for the detection of object information from a monitored zone (108) is provided, wherein the sensor (100) comprises a light transmitter (12) having an associated transmission optics (14) for the beam formation of a transmitted light beam (102, 20, 24) and for a limitation of its beam cross-section to a predefined diameter in a depth of field range; a light receiver (116) for the generation of a received signal from the reflected light beam (112); and a control and evaluation unit (118) for extracting object information from the received signal. In this connection, the transmission optics (14) has at least two optical part regions (18a-b) having different beam-forming properties and the optical part region (18a-b) which acts in a beam-forming manner with respect to the transmitted light beam (20, 24) can be set in order to vary the depth of field range.
