ABSTRACT:
A zone is monitored with an optoelectronic sensor. Light is transmitted in accordance with a structured light pattern in the direction of the monitored zone and is received from the monitored zone. The received light is converted into received signals and the received signals are evaluated with respect to the presence of an object, or with respect to a movement of an object, in the monitored zone. The light is transmitted and/or received in accordance with at least two different light patterns.
