  • Abstract
    A novel fiber Bragg grating acceleration sensor with high frequency in vertical direction and low frequency in horizontal direction based on a structure of stainless steel capillary is proposed. In vertical direction its resonant frequency can reach 2200Hz and in horizontal direction its sensitivity can reach 209pm/g so that we can change the direction of the capillary conveniently according to the practical requirements of high frequency or high sensitivity in seismic exploration.
