| Abstract(in English) | We report the research on ultra-high strain-resolution fiber sensors for static strain measurement with a pair of fiber Bragg gratings (FBGs), one for strain sensing and the other for temperature compensation. The Bragg wavelength difference between the two FBGs is evaluated utilizing a cross-correlation algorithm. A wavelength resolution of 6.7 fm for Bragg wavelength difference is obtained, corresponding to a strain resolution as high as 5.6 nano-strain. The mechanism of suppressing noise by cross-correlation algorithm is also quantitatively analyzed. |
