Design Research of Fiber Bragg Grating Accelerometer
一种新型光纤布喇格光栅振动传感器研究

For the application in civil engineering filed,a novel FBG accelerometer design concept,which can amplify the signal amplitude and broaden the range of working frequency,is presented.An optimal design is conducted.Finally,some performance tests are performed to evaluate the sensitivity,linearity,transverse anti-jamming ability and amplitude-frequency characteristic of the prototype FBG accelerometer with different damping.The result shows that the design concept is feasible and the sensitivity and the upper limit working frequency are respectively up to 90 pm/ms-2 and about 80% of no-damping initial frequency.
