Abstract
A novel dual chirped fiber Bragg gratings (CFBG) accelerometer is proposed in this paper. The method with CFBG instead of FBG has two advantages. One is that the matching relation of the dual CFBG can be easily realized, while the other is that the linear measurement range is larger than that with FBG. The CFBG accelerometer with elastic system composed of a mass block and a steel tube shows good performances such as higher resonate frequency, larger linear measurement range, easily to fabricate, lower cost, and so on. The sensor with a resonance frequency of 3812Hz has a larger measurement range from 0.1g up to 10g.
