| Abstract: | The diffraction integral formulae in spatial-domain or frequency-domain are simply treated and analyzed in this paper.Under some conditions,the diffraction integral formula of a beam through a misaligned opticalsystem with multi-elements could realize the fractional Fourier transform by introducing scale variables. |

| Keywords: | Fractional Fourier transform Misalignment Spatial-domain Frequency-domain Diffraction integral formula |
