Firstly, a single-axis FBG accelerometer with intensity modulation-direct detection interrogation system was put forward and designed in the paper. Experiments with different excitation frequencies were implemented, which demonstrate its good mechanical structure and fabrication technology. Accordingly, a novel tri-axis FBG accelerometer based on the single-axis FBG accelerometer was proposed and a series of periodic vibration tests were finished to prove its performance at different excitation frequencies. The response of the tri-axis vector FBG accelerometer can keep up with the increasing excitation frequency with good signal-to-noise ratio (SNR) within 160 Hz. The suitable measurement frequency range of the accelerator is between 0 and 500 Hz. The cross-axis response among three axes is analyzed. These experiments indicate that horizontal axes have less influence on the vertical axis vibration of FBG.
