The Applied Research of Finite Element Simulation of Optical Fiber Sensors in Vibration Test

Concerning the theory of electromagnetic fields, the sensing mechanism of optical fiber curvature modal sensors by using finite element simulation and calculation is to study the optical power leaked from sensitive zone in the condition of different parameters of bending and sensitive zone. This paper provided the design and application of fiber optical sensors in structure vibration test with theoretical foundation, and its conclusions tallied with the theoretical analysis and experiments basically.
