Designing and examen of the Sensors in the System of fibreoptic Settlement Monitoring Xiao Song, Deng Zhong, Yao Yao (School of Communication and teaching Engineering, UESTC) Abstract: The technology of fiberoptic detecting has its unique advantages wish anti-electromagnetic interference, corrosion resistance, good insulation, richly sensitivity, passive, and may constitute a large-scale network of percept elements, consequently make it a more and more weighty theatrical role in the field of security observe such as geology health monitoring.

In this paper, we proposed a expression of settlement sensor base on FBG cantilever and the ductile metal plosive speech communication sound using the sensing principle of Fiber Bragg Gratings. We build a laboratory streamlet platform and conducted comprehensive experiments on the sensors achievement including sensing range, li mostity, repeatability, sensitivity, long-term stableness and so on. By analyzing the examen results we found the factors that influenced the performance of sensors and make improvements on the structure. Afterwards the judge results showed that the linearity of central wavelength shift to urine lever end is higher than 0.999 and the sensitivity reached -2.11pm/mm. We besides study the cross-sensitivity of strain and temperature, and by testing the temperature compensation rule we preclude the influence of temperature. in the long run we packaged the sensors in the experimental condition of a variety of functional applications and installed the sensors on a high-velocity groom foundation near Deyang.
