Study on Compensated Acceleration Sensor with Fiber Bragg Grating Based on Optical Wavelet Filter

摘要：

Taking into account of compensated structure, especially temperature noise and intrinsic noise, this paper addresses a measuring system of vibration acceleration for acoustic emission signal, in which the distributed high-performance Fiber Bragg Grating (FBG) based on optical wavelet filter is used as measuring probe for the vibration acceleration. Thus influences of lateral sensitivity, temperature noise and intrinsic noise of fiber can be eliminated automatically, and disturbance of imbalance and nonlinear optical signal can also be restrained.
