| 摘 要： | 建立了斜入射情况下毛细波的激光衍射理论。当激光斜入射到几10至几102Hz毛细波上,观察到稳定、清晰的衍射图样,衍射光强分布随着毛细波振幅的变化而变化,并有缺级现象出现,衍射图样具有明显的位置不对称分布。利用傅立叶光学讨论斜入射情况下毛细波的激光衍射,毛细波为正弦型位相反射光栅,给出了毛细波激光衍射的光强理论分布。利用该理论讨论了衍射图样的缺级现象和位置不对称分布,并对衍射图样进行了模拟,理论与实验基本相符。

| Abstract: | The theory to investigate capillary waves using optical diffraction with oblique incidence is proposed.When the laser beam obliquely impinges on capillary waves at a certain angle,steady and visible diffraction patterns are observed.The diffraction intensity will change with the amplitude of capillary waves,and the missing order is formed.Furthermore,obvious asymmetry of patterns is observed.The proposed theory is derived from the theory of Fourier optics,and the capillary wave acts as a sinusoidal reflecti... |
