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。

It is shown that the atmospheric turbulence gives rise to spectral shift and to beam spreading of spatially partially coherent polychromatic light whether the scaling law is satisfied or not.

结果表明，无论是否满足定标律，大气湍流会引起多色部分空间相干光的光谱移动和光束扩展；多色部分空间相干光光束扩展比多色完全空间相干光受湍流的影响小。

It is also shown that the Goos-Hnchen shift of the reflected light beam is the same as that of the transmitted one in the symmetric structure, when the resonance does not occur.

在非共振点处，对称结构中的反射光束具有与透射光束相同的古斯汉欣位移。
