摘要
消偏光纤陀螺,由于单模光纤的不理想,外界磁场会对在光纤中转播的偏振光产生作用(Faraday效应),而产生一个与磁场有关的附加的非互易相位差。基于单色光,对径向磁场作用下的整个陀螺系统进行理论推导、分析,给出仿真结果和实验结果,并提出减小径向磁场作用下的Faraday非互易相位差的方法。
An additive nonreciprocal phase error associated with magnetic field must be generated in Fiberoptic depolarized gyro, which the environment magnetic field has an effect, Faraday effect, on the polarized light that propagates in the imperfect single-mode fiber. Based on monochromatic light, theory derivation and analysis of the whole gyro system that is resulted from radial magnetic field is introduced. The emulation result and the experiment result is given. And the method to reduce the Faraday nonreciprocal phase error resulted from the radical magnetic field is put forward.
