According to the Fresnel-Kirchhoff diffractionintegral and nonlinear paraxial wave equation, we derive the functional relationship of the intensity of hot image and its location.
In this paper, diffractionintegral equations and Bessel Functions are used to getting perfect solution of Fraunhofer ring aperture diffraction, and the diffraction pattern is analysed.
