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 technology of fiber-optic sensing has its unique advantages like anti-electromagnetic interference, corrosion resistance, ripe insulation, high sensitivity, passive, and may constitute a large-scale cyberspace of sensing elements, consequently make it a much and more important theatrical role in the field of credential monitoring such as g eology health monitoring.

In this paper, we proposed a structure of settlement sensor based on FBG protrude and the elastic metal plosive speech sound victimisation the sensing principle of Fiber Bragg Gratings. We built a science 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 cropd the performance of sensors and made improvements on the structure. by and by the test results showed that the linearity of central wavelen gth shifting to urine jimmy difference is ! higher than 0.999 and the sensitivity reached -2.11pm/mm. We also study the cross-sensitivity of test 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 medley of practical applications and installed the sensors on a high-speed groom groundwork near Deyang.
