ABSTRACT:
An optical multiplexing system has several optical sensors connected in parallel between a source and a detector, the path length between source and detector via each sensor being different. The source is modulated at a number of different frequencies, the number being equal to that of the sensors. The output of the detector is an electrical signal which is fed to one input of a number of mixers, one for each frequency. The other input of each mixer receives a different one of each of the frequencies so that each mixer produces an output representative of different ones of the sensors.
