Paper Abstract

A novel Cantilever-based two-axis FBG accelerometer (FBGA) is presented. By installing two fiber Bragg gratings on the cantilever, the proposed FBGA can detect the acceleration, both its magnitude and direction. Theoretical analyses including acceleration response and natural frequency are given. The experimental results show an acceleration sensitivity of 40 pm/g in the X-axis, 18 pm/g in the Y-axis, a directivity of better than 20 dB, and a natural frequency of about 100 Hz. These results agree well with theoretical expectations.
