摘要
在理论上分析了光轴任意方向的单轴晶体的折射率.根据布儒斯特角原理,当线偏振光的电场矢量平行于入射面时,通过测出对样品三个表面的布儒斯特角,就能同时确定单轴晶体的折射率和光轴方向.并利用分光计,在光轴不确定的情况下,测定了方解石的两个主折射率和光轴方向.
The refractive indices of uniaxial crystal with arbitrary optical axis is studied. According to Brewster angle law, the refractive indices and optical axis of uniaxial crystal are determined at the same time by measuring three Brewster angle when the electric field vector of the linear polarized light is perpendicular to the incident planes. In the case of unknown optical axis, two main refractive indices and optical axis direction of the calcite are determined by this method using a spectrometer.
