摘要
介绍了用于光纤陀螺的Lyot型消偏器的基本原理,并给出相应的计算公式。分析结果表明Lyot消偏器的最佳方案为两段光纤长度之比等于1∶2。据此设计的退偏光纤陀螺性能具有较好的一致性。
The principle of Lyot fibre optic depolarizer using in fibre optic gyro was presented in this paper, and the relative formulas were also given. On the basis of this, it was derived that the optimal solution of Lyot fibre optic depolarizer was the ration of the lengths of the two fibre optic was 1 ： 2, The fibre optic gyro designed following the principle showed rather consistency performance.
