| Abstract: | After the integral for the diffraction of a micro elliptical aperture irradiated by a point source is obtained from Kirchhoff diffraction formula,its one numerical calculation method is discussed,and then three kinds of diffraction field is simulated with the Matlab software.These are possibly used in such as the semiconductor laser＇s transmission and transformation and analysis of imaging system＇s aberration and modulation and filtering of optical information processing. |
