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

In this paper, we proposed a structure of settlement sensor based on FBG stick out and the elastic metal plosive speech sound exploitation the sensing principle of Fiber Bragg Gratings. We built a research 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 warpd the performance of sensors and made improvements on the structure. afterwards the test results showed that the linearity of central wavelength shifting! to urine open difference is higher than 0.999 and the sensitivity reached -2.11pm/mm. We also study the cross-sensitivity of pass 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 variety of practical applications and installed the sensors on a high-speed groom buns near Deyang.
