Abstract

For cross-sensitivity problem between strain and temperature in Fiber Bragg Grating (FBG), A FBG signal demodulation system is designed in this paper; signals are acquired and processed by Labview. The experiment of strain sensing with real-time temperature compensation has been studied based on FBG signal demodulation system. The results show that FBG center wavelength drift has good linear relationship with strain. Wavelength resolution of the system is 1pm; detected wavelength range is 54nm. Range of sensing temperature demodulation is -10øC-70øC. The range of sensing strain demodulation is more than 100. When temperature increases from 25øC to 50øC, TC FBG can provide accurate temperature compensation for strain FBG in strain measurement. This system can be used as multi physical parameter monitoring device of the airplane status.
