Abstract

Fibre Bragg grating has become the most attractive intrisic fibre sensor in recent years for various reasons [1-4]. One of the major advantage of this type of sensor is attributed to wavelength encoded information provided by the Bragg grating when affected by the mensurand. Since the wavelength is an absolute parameter, signal from a Bragg grating may be processed such that its information remain immune from power fluctuations along the optical path
