摘要
光纤陀螺光学器件性能指标与陀螺系统性能的相关性问题一直困惑着陀螺与器件研发生产厂家,该问题对中高精度(0.1~0.001°/h)光纤陀螺的综合性能提升,特别是生产批次合格率和批次一致性的提升造成了极大的阻碍。本文就此问题深入分析了影响陀螺三个重要性能指标零偏稳定性、标度因数稳定性、随机游走的噪声因素,与系统光学指标、光学器件指标及光学工艺指标的相关性及关联关系,在此基础上提出了优化的光学器件套件方案和光学匹配方案,并进行了1310nm和1550nm两个波长方案的验证实验,初步实验结果表明相关的套件匹配方案对于陀螺性能提升、光学器件优化选型具有显著的效果。
The problem about the uncertain correlation of the optics device performance index between the performance of the FOG system has puzzled gyro and device research and development manufacturer for a long time. This problem has caused a great obstacle for the performance improvement of high precision(0.1-0.001 °/h) fiber optic gyro, in particular the consistency of the production batch percent pass rate and consistency. Paper on problem in-depth analysis the noise factors that effect FOG's three important performance index: bias stability, sca1 e factor stability, and random walk coefficient. And discussed the correlation and the associated relationship of the system optical index, and optical devices index and the optical process index. On the base above giving a proposed optimization of optical devices Suite programme and optical match programme. The validation experiment of 1310 nm and 1550 nm wavelength programme have made, preliminary experiment results showed that related of suite match programme for gyro performance upgrade, and Optimization of optical devices have a significant effect.
