为了对光栅的衍射性能有更深入的了解,对振幅型光栅的衍射进行了研究.通过对振幅型一维和二维全息光栅的夫琅和费衍射进行观测,拍摄了光栅衍射的夫琅和费衍射图样.从结果发现二维光栅的主极大分布并非两个一维光栅主极大分布的简单相加,而是在二维平面内形成的规则分布,其分布规律与矩孔衍射图样的光强分布有着相似之处.实验结果可以据衍射理论很好地解释,因此,理论与实验是完全一致的.

Diffraction grating to the performance to have a better understanding of the amplitude-type diffraction grating is studied. Type of amplitude one -dimensional and two-dimensional holographie gratings Fraunhofer diffraction to observe the filming of the grating diffraction Fraunhofer diffraction pattern. It was found from two-dimensional grating distribution of the main great two one-dimensional grating is not a great master of the simple sum of the distribution, but in the two- dimensional plane formed by the rules of distribution, the distribution of diffraction patterns and moments of light-hole distribution have'similarities. The experimental results can be very good, according to diffraction theory to explain, therefore, theory and experiment is entirely consistent.
