干涉式光纤陀螺中的Rayleigh散射研究
Research on Rayleigh backscatter of interferential fiber optical gyroscope
摘要
从光的干涉原理出发分析了Rayleigh背向散射对干涉式光纤陀螺性能的影响，得出了散射光强与光纤位置之间的关系式，绘制了散射光强与光纤中位置之间的关系曲线，得到了距离光纤的两个端点越远Rayleigh背向散射对光纤陀螺的性能影响越小的结论。研究结果对分析光纤陀螺的光路误差有一定的参考价值。
Abstract
The influence of backscatter to interferential fiber optical gyroscope (IFOG) is analyzed. The formula between the fiber length and backscatter power is achieved,and the curve is drawn. The result shows the longer apart from the input port,the less influence to IFOG. The research result has some value to analyze the error in IFOG.
