用GRIN透镜斐索干涉仪检测光纤端面的质量

Quality Detection of Optical Fiber Face by Using GRIN Lens Interferometer

采用梯度折射率 (GRIN)透镜干涉仪 ,对用加热、切割和研磨三种方法获得的平面光纤端面进行质量检测 ,得到反映端面不同平整度的干涉图样。实验结果表明 ,GRIN透镜干涉仪结构简单 ,操作方便 ,可作为定性和定量检测光纤端面质量的一种新工具。

A newly developed GRIN lens interferometer was employed to detect the quality of optical fiber faces. This paper introduces the principle of GRIN lens interferometer and exhibits some experimental results, which shows the qualitative discrepancy of fiber faces treated with different methods.
