光纤环温度性能分析软件设计

摘要

The Shupe effect that affects the temperature function of the fiber optic gyroscope(FOG) is introduced.The composition and function of the analysis software of the fiber coil temperature characteristic is discussed.The design is based on the LabVIEW software.The simulation analysis and comparative evaluation with the test results of the FOG is carried out by means of the analysis software of the fiber coil temperature characteristic under two kinds of working conditions that the FOG works in and out of the heat source.The results show that the simulation results are consistent with the test results of the FOG.The analysis software combines the output of the FOG with the finite element analytic result of the fiber coil.The analysis of the fiber coil temperature characteristic is intuitive and effective.%介绍了影响光纤陀螺温度性能的主要因素-Shupe效应,论述了基于LabVIEW软件设计开发的光纤环温度性能分析软件的程序组成和功能,并利用光纤环温度性能分析软件开展了内外热源两种工作条件下,光纤陀螺温度性能的仿真分析及与光纤陀螺测试结果的对比评价.结果表明,仿真分析结果与光纤陀螺测试结果一致,光纤环温度性能仿真分析软件能够将光纤环有限元分析结果与光纤陀螺输出有机结合.
