摘要
本文介绍用双曝光全息干涉显微法测量自聚焦棒透镜折射率分布的测量原理。通过实验测试,表明这种方法具有测量精度高、视场大、放大倍数连续可调和数据处理简单等优点。
A method for measuring the refractive index profile of a graded-index optical fibre using the holographic interference microscopy is presented. Principle of method and measurement results are given. It has the advantages of high accuracy, wide field of view, continuous variable magnification anb simple data processing.
