摘要
根据双轴晶体的锥形折射效应，提出锥角可控的动态外锥折射以及一种实现外锥折射的新方法；选用ＫＮｂＯ３晶体进行实验，不仅观察到外锥折射。
Based on conical refraction effect of biarial crystal, the dynamic outer conical refraction with controllable cone apex angle and a kind of new method to implement the outer conical refraction are presented. The KNbO 3 crystal is used in the experiment, we have not only observed the outer conical refraction, but also obtained the cone apex angle control from 0° to 8°.
