光纤微弯损耗效应及其在检测与自控技术中的应用

Fiber-Optic Microbcnding Loss Effect and Its Application on Testing and Automatic Control Technology

探讨了光纤弯曲损耗机理，提出微弯损耗效应是在光纤弯曲曲率半径小到某一尺寸范围内时，主要由微弯损耗与过渡损耗的综合结果，但在实际应用中，存在着两个困难，一是环境温度变化对传感器结构的影响，二是光源输出功率波动及光路损耗变化等因素，为此，提出了设置参考通道的补偿办法。

Researches the principle of fiber-optic microbending loss effect.Presents that when theradius of curvature reachee,to less than certain value,result is the composite results ofmicrobendingloss and tramIfer loss. But in practice,there are two questions,one is environment temperature,theother is the fluctuation of light source output power and the changes of light loss.So proposes thecompensating method of reference channel.
