Designing and Testing of the Sensors in the System of fiberoptic Settlement Monitoring Xiao Song, Deng Zhong, Yao Yao (School of Communication and Information Engineering, UESTC) Abstract: The applied science of fiber-optic sensing has its unique advantages like anti-electromagnetic interference, corrosion resistance, expert insulation, high sensitivity, passive, and may constitute a large-scale vane of sensing elements, consequently make it a to a greater extent and more important theatrical role in the field of shelter monitoring such as geology health monitoring.

In this paper, we proposed a structure of settlement sensor based on FBG project and the elastic metal plosive speech sound apply the sensing principle of Fiber Bragg Gratings. We built a science lab test platform and conducted comprehensive experiments on the sensors performance including sensing range, linearity, repeatability, sensitivity, long-term stability and so on. By analyzing the test results we found the factors that square upd the performance of sensors and made improvements on the structure. subsequently the test results showed that the linearity of central wavelength shif ting to urine jimmy difference is higher t! han 0.999 and the sensitivity reached -2.11pm/mm. We also study the cross-sensitivity of demarcation and temperature, and by testing the temperature compensation method we preclude the influence of temperature. Finally we packaged the sensors in the consideration of a mixed bag of practical applications and installed the sensors on a high-speed groom foundation near Deyang.
