FBG Close-Loop Dynamic Demodulation Method and System with Temperature Compensation

Abstract:

A FBG fast demodulation system with close loop control is presented. Based on filter edge, the demodulation speed is very high. The system overcomes the strict command on matched FBG fabrication and eliminates the temperature induced error. With close loop control, the temperature induced FBG wavelength shift is compensated well.
