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.
