| Abstract: | For overcoming the complexity of the computation of Fresnel diffraction through a circular aperture and the numerous samples of light wave, the Hankel transformation algorithm,the conversion of 2-D to 1-D and the processing of the spherical wave factor are applied. The simulative demonstration's implement of Fresnel circular aperture diffraction on PC is presented. |
