Abstract

Checking the great generator's vibration online is difficult because of its strong electric and magnetic field so it needs had better no metal in the sensor. We introduce a method of measuring vibration by using FBG and demodulating it by blazed grating and it doesn't use any metal. We present the design method and the theory of demodulation. The results of the experiment show that the vibration amplitude of the exciter matches the detected signal under the stable frequency. The experiment also successfully separated the temperature shift and vibration signal.
