Abstract

A process for evaluating the pulses of electromagnetic radiation in the 0,5 to 1,0 mu m range with a photoelectric evaluation circuit comprising contiguous transmitter and receiver. In order to reduce by at least ten times the previous limit value of about 0,2 milliseconds for the transmission rate, and to bring at the same time the pulse-pause ratio down to > 1:50, this ratio being essential to obtain a large interval between disturbances, it is proposed that, the receiver being driven with light pulses in the microsecond range, the received signal is interrogated at a moment in time when the transmitter is already switched off.
