Abstract

A simultaneous spatial, time and wavelength division multiplexing topology, with combination of a tunable wavelength filter and an interferometric wavelength scanner, is proposed to interrogate a range of in-fibre Bragg grating (FBG) sensors. An eleven-element FBG sensor network based upon this topology is demonstrated for quasi-static strain sensing. Preliminary experimental results show that a strain resolution of similar to 7 mu epsilon with a similar to 30 Hz bandwidth (similar to 1.3 mu epsilon/root Hz) for quasi-static strain measurement has been obtained.
