Paper Abstract

A sensor based on a Bragg grating (FBG) fabricated in Hi-Bi optical fiber allowed measurement of transverse and longitudinal strains. A novel interrogation technique that enables information about transverse and longitudinal strain to be deduced from changes in FBG reflectance spectra is proposed. The scheme enables translation of spectral information into optical power received at a pair of sensor heads.
