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 ∼7 μϵ with a ∼30 Hz bandwidth ( ∼ 1.3 μ∈/√HZ) for quasi-static strain measurement has been obtained.
