Source-noise-induced resolution limits of interferometric fibre Bragg grating sensor demodulation systems

摘要

Curved long-period fibre gratings are described in terms of a new model, based on a matrix method. The variations in the formulation of the main equations, which define the spectral behaviour of a long period fibre grating, are presented. Good agreement between experimental data that had previously been reported and results from the proposed model are obtained.
