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

In this paper, we proposed a structure of settlement sensor based on FBG jut out and the elastic metal plosive speech sound use the sensing principle of Fiber Bragg Gratings. We built a research laboratory 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 fascinated the performance of sensors and made improvements on the structure. after the test results showed that the linearity of central waveleng th shifting to urine prise difference is h! igher than 0.999 and the sensitivity reached -2.11pm/mm. We also study the cross-sensitivity of breeze 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 manikin of practical applications and installed the sensors on a high-speed groom nates near Deyang.
