摘要
折射率是反映介质材料光学性质的一个重要参数,它的测量在生产生活及科学研究中具有重要的意义。本实验尝试采用一种新的方法——等相位法,利用LM2000A光速测量仪对透明固体介质的折射率进行测量,以玻璃砖为例,并对实验产生的误差以及改进方法进行了分析。
Refractive index is an important parameter which reflects the transparent solid dielectric material＇s optical nature. Its measurement has important significance in production life and science. A new method, equal phase method is used in this experiment to measure the refractive index of transparent solid dielectric using the LM2000A model experiment apparatus of light velocity test （set a glass brick as an example）, the errors and its improved methods are also analyzed in this paper.
