正六边孔的衍射场

Diffraction fields of Regular hexagon hole

为了研究正六边形小孔的衍射场,采用波前相因子判断法并考虑到孔径的影响对正六边形小孔的衍射场进行研究,得出正六边形小孔衍射场所含基元成份及衍射场的波前函数、像面上的振幅分布函数和光强分布函数,然后利用数值模拟的方法得出正六边形小孔在像面上的衍射图样;结果表明,在验证衍射理论的同时拓展了衍射的概念,能为深入理解光的衍射提供参考。

In order to study diffraction fields of regular hexagon hole,Based on the method of wave-front phase-factors and considering of the influence of limited aperture of grating, we have study out the diffraction fields by regular hexagon hole which contain components, and offered corresponding integral expressions of the diffraction fields. It derivate formulae of the amplitude distribution of diffraction fields.Finally the amplitude and the length strength parameter distribution along image surface are obtained. Results show that validation diffraction theory.also expand the concept of diffraction. It provides a theoretical basis of light diffraction for the deep understanding.
