摘要
磁光法拉第(Faraday)效应能形成与sagnac效应无法区分的非互易性相移,导致输出误差。首先,建立光纤陀螺磁场模型,获得陀螺漂移与轴向磁场和径向磁场的关系;其次,建立了单轴磁致漂移简易模型,并对单轴简易模型进行仿真,获得线双折射、光纤扭转率和光纤长度与法拉第漂移的关系曲线,同时获得了这些因素对干涉对比度的影响;最后通过实验测量亥姆霍兹线圈在恒流下产生的磁场对光纤陀螺输出的影响,验证了法拉第相移与磁场强度成线性关系,通过对不同屏蔽情况的磁敏感性测试,获得了光纤陀螺的磁敏感性,并验证了光纤陀螺磁屏蔽外壳在削弱法拉第漂移方面有明显效果。
Faraday effect can be formed on nonreciprocal phase shift which is indistinguishable with the Sagnac effect, resulting in the output error, greatly reduce gyro accuracy. By establishing a magnetic field model of FOG get the relationship between gyro drift with axial magnetic field and radial magnetic field is firstly in this thesis. Then, by the establishment of a uniaxial and triaxial magnetic drift caused by simple model, and simulate the uniaxial model to obtain the Faraday drift which caused by the linear birefringence, the twist and the length's change, at the same time,we can access to the interference contrast influenced by these factors. Finally, we imposed a magnetic field of the Helmholtz coil to the FOG to measure the output drift, by this experiment, the fact that Faraday drift is proportional to the magnetic field intensity was proved, and got the magnetic susceptibility of FOG. what's more, it also proved that the magnetically shielded enclosure of FOG works very well.
