Abstract :
Simulation results based on a comprehensive model show that the amount of mode splitting in typical long period fiber grating (LPFG)-based bending sensor rises linearly in small range of bending. According to simulation results, this range of sensing in a typical LPFG-based bending sensor reaches to almost 5m-1. On the other hand, fiber Bragg grating (FBG)-based bending sensor behaves linearly in the wide considered range of bending, K=0-26m-1.
