摘要：
A novel method for achieving high resolution for static strain measurement is proposed and demonstrated. This method is based on the combination of two fiber Bragg grating (FBG) and an all-fiber Fabry-Perot sensor (FFPI) formed by the two FBGs. The wavelength shift of the FBGs is used for determining the fringe number of the interferometic signal while the FFPI and the pseudo-heterodyne are used to carry out high-resolution measurement. The resolution for static strain by the actual measuring is 31 n epsilon.
