| Abstract: | According to light diffraction theory,two methods that are formulary calculation and Fourier transform based on computers and visual programmable language MATLAB to simulate Fraunhofer diffraction phenomena are presented.The Fraunhofer diffraction phenomena of multi-slits（grating） with different number acquired by these two methods are useful not only to apprehend the principle of grating but also to design and use them. |
