The Correction of Nonlinearity in Wavelength Scanning Based on Long-OPD Interferometer for Fiber Bragg Grating Demodulation in Environment With Variable Temperature

The Correction of Nonlinearity in Wavelength Scanning Based on Long-OPD Interferometer for Fiber Bragg Grating Demodulation in Environment With Variable Temperature

Fabry-Perot (F-P) filter based fiber Bragg grating (FBG) demodulation has been widely applied in many areas. However, the F-P filter suffers from random fluctuation in wavelength scanning when the ambient temperature changes severely, which reduces the demodulation accuracy inevitably. In this paper...
