Paper Abstract

The imperfect fiber in fiber optic gyro (FOG) can not keep the polarization of light under the effect of external magnetic field, and the output of FOG varies. Based on analyzing the output of FOG collected at different placed modes but with the same external magnetic field and the same magnetic shielding proposes the scientific way of how to place FOG when we are testing the magnetic shielding effectiveness. This is also useful to guide the utilization of ANSYS in simulating the design and analyzing the magnetic characteristic of the magnetic shielding instrument (MSI) for FOG.
