On the basis of Fraunhofer diffraction theory, the diffraction patterns of a Varied Line-space (VLS) grating were obtained for incidencebeam in parallel and uniform.
基于夫琅禾费衍射理论，推导了平行光入射变栅距光栅后衍射光强的角度分布。

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.
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 effects produced when a beam of light falls on a crystal for varying angles of incidence can be readily visualized by a geometrical representation.
