Abstract: An optoelectronic sensor (10), in particular a laser scanner, for the detection of objects in a monitored zone (20) having a more than one scanning plane is provided which comprises a light transmitter (12) for the transmission of a light beam (16), a drive (28) for generating a rotational movement, a deflection unit (18, 62) rotatable about an axis of rotation (30) by the drive (28) for the periodic deflection of the light beam (16), a light receiver (26) for generating a received signal from the light beam (22) remitted or reflected from the monitored zone (20), and comprising an evaluation unit (46) which is configured for the detection of the objects on the basis of the received signal, wherein the deflection unit (18, 62) can be tilted in order to vary the scanning plane. In this connection the drive (28) tilts the deflection unit (18, 62) at the same time as the rotational movement.

Abstract: The invention relates to an optoelectronic sensor for detecting objects in a monitored zone that has a light transmitter; a deflection unit for deflecting the transmission light beam without mechanical moving parts or at most with micromechanical moving parts to scan the monitored zone; a light receiver; and a control and evaluation unit that is configured to determine information on the objects by means of the reception signal received by the light receiver. The sensor has at least one reference target that receives at least a portion of the deflected transmission light beam at at least one deflection angle of the deflection unit or returns it to the light receiver in order to generate a reference signal; and the control and evaluation unit is configured to check the operability of the deflection unit by means of the reference signal.
