摘要
在分析光纤环对陀螺整体性能影响的基础上,提出将BOTDA光纤传感技术用于光纤环质量检测。通过对光纤环的在线检测、热应力检测和骨架性能影响测试,能及时发现并消除光纤绕制中的应力尖峰及换层现象,消除由骨架、热应力引起的光纤应力曲线反转现象。
Based on the analysis of the influence of fiber coil on the overall performance of fiber optic gyro(FOG) ,we proposed to assess the quality of fiber coil by utilizing the Brillouin opti-cal time-domain analysis (BOTDA) optical fiber sensing technology .Through the on-line tes-ting ,thermal stress testing and framework performance testing for fiber coil ,we could discov-er and eliminate the stress spike and layering switch phenomena in time ,also the optic fiber stress curve reversing induced by framework and heat stress could be removed .
