Research and application of fiber Bragg grating geophone
|
Abstract:
Fiber Bragg Grating seism demodulation technology is the newest kind of seism demodulation technology.The result of the experiment indicates that the Fiber Bragg Grating geophone has wider bandwidth,better stability,higher sensitivity,and a perfect kind.In this paper,the basic principle,theoretical calculation and operation of the FBG sensing are mainly described.The study and application of the FBG seismometer are provided.
