对于所有小于临界角的入射角，则既发生反射，又发生折射。
At all angles less than the critical Angle, both reflection and refraction occur.
利用稳态相位法研究了当入射角小于全反射临界角时双棱镜结构中透射光束的古斯汉欣位移。
The Goos-Hnchen shift of the transmitted light beam in a two-prism configuration is investigated by stationary-phase approach when the incidence angle is less than the critical angle.
同时还采用了全反射临界角法进行自动聚焦。
In addition, critical Angle method is introduced for automatic focusing.
