摘    要:通过对高折射率玻璃微珠在激光照明下形成的二次彩虹的实验研究,提出了一种激光照明下高折射率玻璃微珠二次彩虹条纹图的获取装置。以艾里的虹理论为基础,提出了一种由二次彩虹条纹图确定最小偏向角的方法,实现了高折射率玻璃微珠折射率的测量。实验证明,该方法的测量精度为0.4%,测量结果得到了V棱镜测试方法的证实。

关 键 词:高折射率玻璃微珠  二次彩虹法  最小偏向角  折射率

Abstract:A new experiment setup to be used to obtain the fringe of secondary rainbow of the high refractive glass beads irradiated with laser is presented. The fringe of secondary rainbow of the high refractive glass beads is analyzed by using Airy rainbow theory, and a method to be used to determine the position of the minimum deviation an gle according to the secondary rainbow is proposed. The calculation of refractive index is implemonted according to the minimum devlationangle measured on our experiment setup. The refractive index measurement result shows that the precision of our setup is 0.4%. And this result has been proved by Vshape prism methed.
Keywords:high refractive index glass beads  secondary rainbow method  minimum deviation angle  refractive index
