Abstract

Simultaneous interrogation of interferometric fiber-optic sensors by means of spectral signal processing is described. The method provides highly accurate nonincremental measurements of the optical path difference for each sensor in the network and consequently the external parameter affecting this sensor. The combination of different multiplexing techniques results in combining of several tens of sensors in the single network.
