Joseph von fraunhofer(1787-1826 )

The difference of Fraunhofer diffraction between Information Optics and Physical Optics is analysed, the consistence of which is pointed out about one single object.

分析信息光学和物理光学中夫朗和费衍射的差别 ,指出在研究单个物体的夫朗和费衍射二者的一致性 ,根据普适的夫朗和费衍射的定义 ,导出夫朗和费衍射的近似条件。

It is pointed out that the methods of the approximate treatment of the Fraunhofer diffraction under spherical wave illumination in literatures [1-7] are not very proper.

本文认为文献[1]～[7]对球面波照明下的夫朗和费衍射的若干近似处理方法不是十分妥当的。
