English: Remove Spatial Aliasing in the Fresnel Diffraction computation. File describes light diffraction at distances of 0.1cm - 1cm in steps of 0.1cm from the circular aperture of diameter 0.5micron at a wavelength of 0.6micron (red-light). The calculation used a 512x512 grid to represent this problem, and spatial aliasing has been avoided.
I am uploading it again as wikipedia messes up the earlier upload under name Airy.gif
