Abstract: A novel design of fiber Bragg grating (FBG) based accelerometer is proposed in this paper. The chirp-free mechanism on the FBG sensing element is the methodology employed in this design. The sensor has the flexibility to apply different mechanical parameters, and it shows excellent performance to different applied signals. The performance is then optimized by varying different configuration of the sensor. Good sensitivity (18με/g) and signal-to-noise ratio (20.68dB re nm/g) is easily achieved. Maximum input signal frequency up to 150Hz is able to be caught up by the specific configuration of the accelerometer. The accelerometer also has the capability of capturing a full sine wave input signal with the maximum peak-to-peak amplitude up to 3.9nm.
