| Abstract: | Fourier transform of any grade can be realized in the free space of Fres-nel diffraction on spherical wave illuminating objects. Consistence is shown between Fresnel diffraction and fracional Fourier transform. Computer simulation proves the feasibility and reliability of the theory. |
