sinusoidal radiation chopper

The proposed theory is derived from the theory of Fourier optics,and the capillary wave acts as a sinusoidal reflection phase grating for the laser beam.

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。

In this paper, the theory of reftaction was brief introduced on 22°halo and parhelion, it is proved that three same light sun is present in the sky is not produced for diffraction of sine grating.

简述了２２°晕和近假日的折射理论，论证了“三日同晖”不是正弦光栅衍射形成的，提出了２２°晕和近假日的折射─衍射理论。
