Dynamic demonstration of Fresnel single slit diffraction;

Based on Fresnel-Kirchhoff integral theorem of plan screen diffraction, asymrtotic approximation to special function and the method of stationary phase have been discussed, and the integral formula of optical-intensity distributed-function of single-slit Fresnel diffraction is introduceed.
