OPTOELECTRONIC SENSOR AND METHOD FOR DETECTING MEASUREMENT INFORMATION FROM A SURVEILLANCE AREA

摘要

PROBLEM TO BE SOLVED: To provide a laser scanner allowing easy handling of measurement data.SOLUTION: There is provided a photoelectric sensor 10 for detecting measurement information from a monitoring area 20. The sensor 10 comprises: an optical receiver; and an evaluation unit for generating measurement information angularly decomposed on the basis of an angle origin from a received signal of the optical receiver. The evaluation unit of the sensor is configured so as to move the angle origin to an angular position 44 indicated by an optical marker 46 marked by a user.
