キーワード:Long distance sensing, FBG demodulation, Rayleigh scattering, wavelength measurement

A novel long distance fiber Bragg grating (FBG) demodulation scheme which can eliminate the influence of Rayleigh scattering is proposed. It can detect changes of FBG reflection wavelengths 100km away with an accuracy about 20 pm.
