The invention relates to an opto-electronic sensor arrangement (10) with an optical transmitter (20) and an optical receiver (30), such that the optical transmitter (20) and the optical receiver (30) are so positioned that they either form an optical scanner designed as an optical scanner with background gating or form a reflecting light barrier in conjunction with a reflector (60), and such that the optical receiver (30) has a detector (32) in which successive images of the light beam (30a) reflected from the object (50) are detected and are compared in an evaluating unit (36), and the outcome of the comparison provides information on the movement of the object (50) relative to the optical receiver (30), so that the detector exercises a movement function. The invention also relates to a process for detecting the presence and movement of an object (50), in which a light beam (20a) emitted from the optical transmitter (20) of an opto-electronic sensor arrangement (10) is reflected from the object (50) and detected in an optical receiver (30), such that the optical transmitter (20) and the optical receiver (30) are so positioned that they either form a light scanner in the form of a light scanner with background gating or form a reflecting light barrier in conjunction with a reflector (60), and such that the optical receiver exhibits a detector (32) in which successive images of the light beam (30a) reflected by the object (50) are detected and are compared in an evaluating unit (36), and the outcome of the comparison provides information on the movement of the object (50) relative to the optical receiver (30).
Opto-electronic sensor arrangement (10), with an optical transmitter (20) and an optical receiver (30) which are positioned relative to each other so as to create an optical scanner which takes the form of an optical scanner with background gating, such that the optical receiver (30) has a detector (32) in which successive images of the light beam (30a) reflected from the object (50) are detected and are compared in an evaluating unit (36), and the outcome of the comparison provides information on the movement of the object (50) relative to the optical receiver (30), with the result that the detector exercises a movement function.
Opto-electronic sensor arrangement (10), with an optical transmitter (20) and an optical receiver (30) which are positioned relative to each other so as to form a reflecting light barrier in conjunction with a reflector (60), such that the optical receiver (30) has a detector (32) in which successive images of the light beam (30a) reflected from the object are detected and are compared in an evaluating unit (36), and the outcome of the comparison provides information on the movement of the object (50) relative to the optical receiver (30), with the result that the detector exercises a movement function.
Process for detecting the presence and movement of an object (50), where a light beam (20a) emitted from the optical transmitter (20) of an opto-electronic sensor arrangement (10) is reflected from the object (50) and detected in an optical receiver (30), such that that the optical transmitter (20) and the optical receiver (30) are so positioned that they either form a light scanner in the form of a light scanner with background gating or form a reflecting light barrier in conjunction with a reflector (60), and such that the optical receiver exhibits a detector (32) in which successive images of the light beam (30a) reflected by the object (50) are detected and are compared in an evaluating unit (36), such that the outcome of the comparison provides information on the movement of the object (50) relative to the optical receiver (30).
