Abstract
Aiming at the existence of external magnetic field has negative effects on the performance of highprecision fiber-optic gyroscopes(FOGs)
a method for optimizing design of magnetic shielding structure for FOGs is proposed
analyze on theory of effect of each parameter on entire magnetic shielding efficiency in FOGs magnetic shielding structure
establishing models and scanning simulations. Eventually
using the results of simulations
the structure of magnetic shielding can be raised as a combination of various parameters. This method can providesome references for magnetic shielding structure design and optimization of the FOGs.
