| Abstract: | The sensing probe of the fiber Bragg grating geophone is made up of fiber Bragg gating. The information which it collects is embodied in wavelength. The modulation-demodulation is accomplished by fiber Bragg gating geophone directly. Compared with traditional geophones,it has higher resolution,wider bandwidth,higher accuracy and better immunity to electromagnetic interference. The system architecture,operating principle and structure design of the sensing probe of the fiber Bragg gating geophone are explained emphatically. |
