| Abstract: | Analysis of the Yellow River dam deformation monitoring of the status quo shore, and the fiber grating sensor operating principle, according to two features, combined with the specific situation of the Yellow River dam is designed to facilitate installation of the FBG deflection instrument. Through laboratory calibration in order to get FBG deflection instrument, ＂wavelength difference - the angle＂ relationship, as a basis for algorithm design parameters. |
