The sensor (14) has a light transmitter (16) for transmission of light signals into a monitored zone (18), where the light signals are generated on the basis of an output signal (60) provided with an offset (22). A light receiver (20) receives the light signals, and an interference suppression unit measures current interference in a frequency region of power spectrum repeatedly or continuously. The suppression unit analyzes the interference in time- and/or frequency domain, and compensates the interference based on the interference analysis. An independent claim is also included for a method for interference suppression in an optoelectronic sensor. |
