Abstract
The physical meaning of the analytic expression for aperture Fresnel diffraction are discussed, the difference between the accurate (in Fresnel approximation) and approximate solution are pointed out, the calculated results are compared to the other results which basing on numerical integration calculation. The correctness, of analytic expression for aperture Fresnel diffraction is proved.
