Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an object detecting and distance measuring method.SOLUTION: Provided is a photoelectronic sensor 10, particularly a laser scanner, for detection and distance measurement of an object present in a monitored area 20. The sensor 10 comprises: a light emitter 12 to emit an outgoing beam 16 modulated using a pseudorandom code string; a deflecting unit 18 to periodically deflect the beam toward the monitored area 20; an optical receiver 26 to generate a reception signal; an A/D converter 36; a correlation unit 40; and an analysis unit 32 configured to determine a measurement of the distance to the object.
