| Abstract: | Based on Fesnel _ kirchoff formula, diffraction field by a plane aperture on image plane of the point light source is derived ,which shows that it is also a kind of Fruanhofer _ diffraction under given conditions. The truncation error of approximation is discussed and application to teaching is explained as well. |
