| Abstract: | A numerical simulation is adopted in circular aperture diffraction.The change of diffraction fringes and Airy disk size is observed by adjusting the parameter of incident wavelength,size of circular aperture,etc.We also discuss the influence of Airy disk size on image resolution.These are helpful to further study the relevant diffraction experiment,and the diffraction theory and technology.This kind of computer simulation method extends the study ways of the diffraction problem,and has some potential applic... |
