摘要：

A vibration measuring system based on a matched-fiber Bragg grating (FBG) is demonstrated, and the cross sensitivity of the temperature and strain was reduced by packaging the matched-sensing and interrogation FBG in the same shell, theory, system structure, and experimental results are presented. The experimental results demonstrated that the system has a good response to the 8-80 Hz vibration signal; it responds well to an acceleration of as low as 0.05 m/s(2), the system was deployed in a coalmine,and good experimental result were received. Because the system has the advantage of intrinsic safety and an easy multiplex, it has good prospects in the mining and petrochemical industry.
