A New Type of Accelerometer Based on Fiber Bragg Grating

Abstract:

Fiber Bragg Grating has advantages of high resistance to electromagnetic interference and high accuracy, which could obtain high-precision detection of the vibrations. A new type of accelerometer based on Fiber Bragg Grating (FBG) is proposed in this paper. The mechanical model of the accelerometer is designed as a single-degree-of-freedom system. The experiments show FBG accelerometer system has excellent stability and high durability. The acceleration sensitivity of the FBG accelerometer is 31.2pm/G.
