Opto-electronic sensor for detecting objects

摘要

The optoelectronic sensor (10) has a light transmitter (12) that transmits light beam (16), a drive unit (28) that generates rotational movement, a deflection unit (18) rotatable about an axis of rotation through the drive unit for periodic deflection of light beam, and a light receiver (26) that generates received signal from light beam (22) re-emitted or reflected from monitored zone (20). An evaluation unit (46) detects objects based on received signal. The drive unit tilts deflection unit at the same time as the rotational movement to vary the scanning plane. An independent claim is included for a method for detection of objects in a monitored zone having more than one scanning plane.
