This study presents the development and performance evaluation of a temperature and chirp compensated fibre Bragg grating (FBG) geophone for improved seismic detection. The proposed FBG geophone utilized a rubber diaphragm to enhance vibration sensitivity. A differential FBG technique with two-point bonding was employed to eliminate chirping effects and achieve temperature compensation. The fabricated FBG geophone demonstrated a vibration sensitivity of 68.77 pm/g across the range of 1-54 Hz. Moreover, the proposed design exhibited a low cross-axis sensitivity of 3.68% and insignificant temperature sensitivity of 0.25 pm/degrees C. These findings significantly enhance the overall performance of the proposed FBG geophone for seismic detection.
