对傍轴标量衍射理论的修正分析

Analysis and Correction of the Theory of Scalar Diffraction

基尔霍夫衍射理论是根据格林定理和光的波动方程,选取合适的格林函数得出的.但基尔霍夫衍射理论存在内部的不自洽性,文章选取不同的格林函数对这种不自洽性进行了修正,并将修正结果应用于双缝衍射过程.结果表明:得出振幅不同的复函数,最终得到同样的衍射花样.

Kirchhoff diffraction theory is based on Green theorem and light wave equation of the suitable Green function. But Kirchhoff diffraction theory exist not-self-consistent,so we correct the not-self-consistent by different Green function,and the correc- tion results used in flat screens are compared.
