Zusammenfassung:The system comprises at least one transmitter (13) at one end of the monitored zone (11), e.g. a light grid with a group of interspaced transmission elements (15), transmitting electromagnetic radiation into the monitored zone. At least one reflector (17) is fitted at the opposite end of the zone, and at least one receiver (19), with one or more receiver elements (21), receives the reflected radiation and is coupled to an evaluator (23). The transmitter, reflector, and receiver are so arranged that, part of the transmission elements is imaged on the receiver element and can be checked by the evaluator during monitoring. Independent claims are included for method of detecting penetrating objects.
