Abstract:
A highly sensitive fiber Bragg grating (FBG) geophone with temperature insensitivity has been developed for low-frequency seismic detection. This geophone utilizes a rubber-based diaphragm combined with a differential FBG technique to enhance vibrational sensitivity and eliminate temperature effects. This innovative method achieves a high vibrational sensitivity of 169.71 pm/g across a frequency range of 1–36 Hz, while a low temperature sensitivity of 1.21 pm/°C is obtained over the range of 10~^{\circ } C– 40~^{\circ } C. Frequency spectrum comparisons demonstrate that the FBG geophone performs comparably to conventional electrical geophones.
