光纤陀螺的温度实验与仿真分析

摘要

Thermally induced non reciprocity phase shift has affected working-accuracy of fiber optical gyroscope (FOG). By the analysis of this phase shift, the relationship of it and temperature characteristic (TC)in FOG were established. Based on it, the temperature experiment (TE)and computer simulation analysis (SA)have been carried on. The results show that SA of temperature distribution(TD)in FOG can be realized, and the way of TC and SA can help to clear up TC in FOG.%热致非互易相移的存在影响了光纤陀螺的工作精度.通过对热致非互易相移的分析,把握了该相移与光纤陀螺温度特性的关系.在此基础上,进行了光纤陀螺的温度实验与仿真分析.结果表明,仿真分析光纤陀螺的整体温度分布是可行的;温度实验与仿真分析相结合的办法有助于光纤陀螺温度特性的把握.
