光轴任意取向的单轴晶体间光的传播

在晶体光学、薄膜光学和光学偏振仪器的设计以及激光通讯元件的研制过程中 ,经常需要确定在两各向异性的单轴晶体间光的传播方向 ,特别是e光 (非常光 )的轨迹问题 .对此 ,虽然国内外已有一些文献进行过讨论 ,但所提出的解决问题的办法 ,其运算过程都十分繁琐 ,且晶体光轴的取向往往是所限定的 .本文通过研究、分析和计算 ,提供了一种较为简便的在光轴取向任意的各向异性的单轴晶体间精确求解光线轨迹的方法 ,并着重提出了在计算过程中应该注意之处 ,最后给出了计算实例 .

Transmission of extraordinary light betwen Uniaxial crystal when the direction of optical axis is discretional

In crystal optics,thin film optics,optical polarzing apparatus design and during the development process of laser communicate component,it is necessary to determine the transmission direction of light between two anisotropy uniaxial crystal,especially the trace of the extraordinary light.Though some former papers have talked about this issue,their solutions and calculate methods were all very fussy and the tropism of crystal optic axis is definite. This paper provided a simple method of calculating the propagation direction of extraordinary light in anisotropy uniaxial crystal when the direction of optical axis is discretional.The author also brings forward the critical point during the calculating process and finally gives out the example of calculation.
