Abstract: At first the integral expression of the diffraction field generated from a rectangular aperture irradiated by a monochromatic point source is expressed from the formula of Fresnel�Kirchhoff diffraction, then the calculation expressions for Fresnel diffraction field and its peculiar circumstance Fraunhofer diffraction field are deduced. Next the paraxial area diffraction patterns of the corresponding light fields are simulated with the Matlab software from the calculation expressions, and the simulation test verifies that the deduced expressions are effective and reliable. These are conducive to further research related to diffraction theory and technology.
