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-fiber 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 approximately 7 (mu) (epsilon) with an approximately 30 Hz bandwidth (approximately 1.3 (mu) (epsilon) /(root)Hz) for quasi-static strain measurement has been obtained.
