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, salutary 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 s urety monitoring such as geology health monitoring.

In this paper, we proposed a structure of settlement sensor based on FBG protrude 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 influenced the performance of sensors and made improvements on the structure. later on 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 phone line 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 salmagundi of practical applications and installed the sensors on a high-speed groom rear end near Deyang.
