【摘要】 本文根据双轴晶体的锥形折射效应，提出了动态外锥折射以及一种实现外银折射的新方法。选用KNbO3晶体进行实验，不仅观察到外银折射，而且实现0至8度范围的动态锥折射。更多还原

【Abstract】 Based on conical refraction. effect of biaxial crystal. in this paper, we give dynamicouter conical refraction which its cone apex angle can be controlled, and a kind of new methodwhich accomplishs outer conical refraction. Selecting KNbo3 crystal to do this experiment. Wehave not only observed the outer conical refraction, but obtained the cone apex angle control from0° to 8°, is can be developped many new applied technigues.更多还原
