Magnetic Shielding Design Applied Research Fiber Optic Gyroscope

为解决高精度光纤陀螺对静磁场敏感的问题,设计了一种多层结构磁屏蔽体,并通过理论计算分析了屏蔽体不同结构、不同厚度对磁场的屏蔽效能。通过实验测试屏蔽体磁场的屏蔽效能,发现与理论计算结果能够较好地吻合,有效降低了光纤陀螺的磁场敏感度。

In order to solve the high-precision fiber optic gyroscope sensitive issue of the static magnetic field, the design of a multi-layer structure of magnetic shield, and calculate the theoretical analysis of the different structures shield, different thickness of the magnetic field shielding effectiveness. Through experimental test magnetic shield shielding effectiveness, discovery and theoretical results can better fit, effectively reducing the magnetic field sensitivity of fiber optic gyroscope.
