Abstract
This paper introduced an optical setup to perform fractional Fourier transformation by Fresnel diffraction with a converging spherical wave illumination.In order to realize the arbitrary order fractional Fourier transformation,the diffraction distance q,the locations of point light source and lenses must satisfy the conditions,formulated by this paper.
