Device for optical measurement of transmission path of compensating optical sensor system, has reflector changing spatial distribution of light of transmitter on receiver, and compensation window reducing intensity of light on receiver

摘要

The device has a compensation path formed in a form of a transmission path (I3) over a compensation transmitter (K) into a receiver (D). The compensation transmitter is placed in a compensation transmitter cavity (CAV-K). The compensation path includes a reflector (R) and a compensation window (WK). The reflector changes spatial distribution of light of the compensation transmitter on the receiver. The compensation window reduces the intensity of light of the compensation transmitter on the receiver.
