摘要 运用琼斯矩阵,分别建立了轴向磁场作用下,单消偏陀螺系统和双消偏陀螺系统产生Faraday非互易相位差的理论模型.导出了两种系统的非互易相位差的表达式,并对其进行理论分析和仿真,最后给出两种系统轴向磁场作用下的实验结果.提出:采用双消偏系统并使得两个消偏器的45°误差之和趋于0,可以在很大程度上减小消偏陀螺的轴向磁场灵敏度. The theoretical models of Faraday nonreciprocal phase error which is generated by axial magnetic field in Single-Depo-Ⅰ-FOG and Twin-Depo-Ⅰ-FOG are founded respectively through using Jones Matrix. The nonreciprocal phase error expression of the two types system is derived. Then the theoretical analysis and the emulation result are given. Finally, the experiment results about the two systems operated in axial magnetic field are brought out. And it is put forward that using Twin-Depo-Ⅰ-FOG system and making the two Lyot depolarizers' error sum tend to 0 may decrease the Fiber-optic depolarized gyro' axial magnetic field sensitivity to a great extent.
