Abstract

This paper carries out theoretical research and numerical simulation on the temperature characteristics of LPFG magnetic field sensor based on magnetic fluids. The simulation results show that the change of ambient temperature can make coupling resonance wavelength of the long period fiber grating drift, change the refractive index of magnetic fluids, which affects the measurement precision of the magnetic field. Our research has a certain significance for the practical application of LPFG magnetic field sensor based on magnetic fluids.
