Paper Abstract

A three-axis fiber Bragg grating for the measurement of acceleration is reported. Results obtained using intensity modulation-direct detection (IM-DD)method demonstrate a demodulated signal output range of 1.87Hz~80Hz.Modal analysis and harmonic analysis are performed utilizing finite element analysis method. The strain change is proportional to the acceleration. The sensitivity is 55.3με/g. Low cross-axis sensitivity is obtained. Arrays of such devices can be utilized in a variety of applications such as structural monitoring.
