Analytic Expression for Disk (Sphere) and Annular Aperture Fresnel Diffraction
The amplitude and intensity analytic expressions for disk (sphere) and annular aperture Fresnel diffraction are given on the base of scalar diffraction theory. The intensity distribution curves are compared with the other examples and results in the references. It is pointed out that the non-diffracted beam is a kind of Fresnel diffraction phenomenon.
