ABSTRACT:
An optoelectronic sensor includes at least one light transmitter for the transmission of light signals into a monitored zone, at least one light receiver for the reception of light signals transmitted from the light transmitter and a control device for the generation and/or influencing of the light signals and for the generation of an object detection signal in the case of the presence of an object in the monitored region in dependence on the output signals of the light receiver. In this connection, the light signals transmitted into the monitored zone by the light transmitter are each generated by an output signal modulated in accordance with the spread spectrum method using a random pseudo-noise code.
