| 中文摘要: |
| 为了确定位于石英晶体入射面内光学轴的位置,采用自然光沿石英晶面以一定的入射角斜入射,并根据自然光在石英晶体内的传播特性,测量出o光和e光出射光线间的垂直间距以及界面上两出射光点的间距,运用几何作图法,通过计算给出光学轴位于石英晶体入射面内的情况下的理论一般公式,且以实验得以验证,从而提供了一种可用光学法确定光轴位置的方法。 |
| 英文摘要: |
| In order to determine the place of the optic axis of the quartz crystal located in its incident plane,natural light was incident along the surface of the quartz crystal with an incident angle.According to the character of propagation of natural light in the quartz crystal,both the vertical distance along with output direction and the distance of two points on the output surface between ordinary ray and extraordinary ray are measured.Using the geometrical method,a general theoretical equation for the place of optical axis of quartz crystal located in its incident plane was put forward.The results are accorded with the experiment.So a method using optical method to determine the place of the optical axis has been proposed. |
