| 摘 要： | 本文在简述逆几何不迩理论基础上，讨论了如何结合计算机图像处理技术根据光线轨迹得出光媒质的剖面折射率分布方法，并且用在改型干涉显微镜基础上建立的ＣＣＤ摄像显微镜实验装置作出验证，从而也提出一种光纤剖面折射率分布测量的简便，易行，精度可靠的新方法。本文介绍的新方法对如何保证目前已被越来越普遍地应用于光通讯和光纤传感器中光纤性能的主要参数检测有十分显著的意义。

| Abstract: | In this paper,a method for measuring refractive index profile of optic inhomogeneous media is suggested on the base of inverse ray optics and image processing technique by computer.Meanwhile the method is tested by a CCD camera microscope which is set up on a modified interference microscope,then it is proved that the method may be simple and easy to perform and high accurate.The method is significant to inspect main parameter of optic fibre,which is more and more generally used in optic communication and fibre sensors. |
