| Abstract: | Two methods (direct calculation and Fourier transform) based on MATLAB to simulate the process of Fraunhofer diffraction are presented. The former is only applied to show the diffraction patterns of some simple apertures, of which the diffraction equations can be exactly deduced by mathematic calculation. The latter can be used to deal with the simulation of Fraunhofer diffractions of any complex obstacle. |
