摘要
本文介绍了采用干涉系统,通过目视判断直线型干涉条纹的方向变化从而确定棱镜相应的空间位置的方法。借助高精度的测角仪器,就可测量棱镜的顶角和最小偏向角,从而得到光学玻璃的折射率。本方法简便、快速、精度高。
This paper describes an interferometric system. The spacial position of a prism can be determined with the naked eye by measuring the change of the direction of the interference fringe system. With the help of a precise angle-measuring device, the apex angle and the minimum deviation angle of the prism can be measured; hence the optical refractive index of the glass. This device is simple to construct, rapid to manipulate and of high precision.
