Abstract :
With the higher sensitivity of the auto tracking working point FBG dynamic strain measurement system, the FBG acceleration system, which is based on a cantilever beam, was realize, the lower sensitivity, brought by higher resonant frequency, was improved. The characteristics of the system are higher working frequency, bigger dynamic range, higher precision, higher stability, strong anti-interference ability and temperature compensation, etc. It has a promoting future.
