通过对光纤环进行应力分布测试和筛选，实现了改善光纤陀螺性能的目的。分析研究了由应力作用产生的光纤环非互易性对陀螺输出特性的影响，采用光纤应力分析仪对光纤环进行应力测试和筛选。并将经过光纤环在线测试和热应力测试筛选后的光纤环组装成陀螺进行零偏实验。实验结果表明：采用应力分析仪能够有效对光纤环进行应力测试和筛选，经过筛选后组装的光纤陀螺精度有了明显改善，全温范围内零偏稳定性可达0.08(°)/h。对后续高精度光纤陀螺研制有一定的借鉴意义。

In order to improve the performance of the FOG, the suitable fiber coil were chosen through the fiber coil strain distribution measurement. In this article, the impact of fiber coil non-reciprocal on the gyro output which generated by strain were studied. Based on the analysis, the strain of fiber coil was tested and the appropriate samples for FOG were selected using the fiber strain analyzer to assemble and install the selected fiber coil for bias experiment. The results show that, strain tests are effectively carried out and the appropriate samples were selected using the strain analyzer. Performance of FOG has been significantly improved with the measurement and select of fiber coil strain distribution, bias stability over the full temperature range is up to 0.08 (° )/h, which has important guiding significance for the development of high precision FOG.
