Optoelectronic detector for marks on contrast model, has transmitter and receiver forming distance sensor element and also linkage of detected distance value and amplitude value for elimination of disturbing signal portions

摘要

Optoelectronic detector (1) has transmitter (4) and receiver (6) which form distance sensor element, which works according to phase measuring principle. A linkage of detected distance value and amplitude value of the transmitting signals of the receiver takes place, for the elimination of disturbing signal portions, during the contrast model detection in the evaluating processor unit (8).
