由光纤Bragg光栅制成的地震检波器
其采集的传感信息包含在波长上
直接对波长进行调制解调
具有分辨率高、精度高、抗干扰能力强和频带宽等优点。文章研究了光纤Bragg光栅地震检波器
给出其重要参数
并提出了一种新的光纤Bragg光栅地震检波器的解调方案。为光纤Bragg光栅地震检波器的研究以及实际应用提供了依据。
Made up of Fiber Bragg Grating(FBG)
the geophone collects
modulates and demodulates directly the sensing information embodied in wavelengths.It has the advantages of higher resolution
higher accuracy
better immunity against interference and wider bandwidth.In this paper
the FBG-based geophone is described and its principal parameters given.A new demodulation scheme for the geophone is presented
which provides the basis for its study and practical applications.
