摘要:
光纤环制作的核心工艺就是光纤线圈的绕制,针对光纤环绕线机中存在的张力控制不对称性问题,提出了一种基于布里渊光时域分析方法检测光纤线圈应力分布状态,从而回馈和指导绕线机张力调整的方法。实验结果表明,以上方法明显改善了光纤环的应力分布状态,有效提高了光纤环成环后的质量,对提高光纤陀螺的精度起到了重要作用。

Abstract:
The key technique in fabrication process of fiber ring is the winding of fiber coil. Aiming at the unbalance of the tension control in winding machine for fiber ring, an adjusting method for the tension control is put forward based on brillouin optical time domain analysis method on detecting the stress distribution of fiber coil. The experimental results show that these ways have effectively improved the stress distribution of fiber coil and the quality of fiber coil, which plays an important role in improving the precision of FOG.
Key words:  FOG  Fiber coil  Tension  Stress
