- All-fibre interrogation technique for fibre Bragg sensors using a biconical fibre filterPublication . Lobo Ribeiro, Antonio B.; Ferreira, L. A.; Tsvetkov, M.; Santos, J. L.A passive self-referencing all-fibre technique for Bragg wavelength shift detection using a biconical fibre filter is described. This filter, basically a tapered depressed-cladding fibre, exhibits a periodic spectral power dependence which permits direct tracking of wavelength shifts in a 20nm unambiguous range. Dynamic strain resolution of 1.5 μstrain/√Hz has been achieved.
