Compared with Fresnel diffraction integral,the fractional Fourier transform (FRT) by a Lohmann′s type II system and Fresnel diffraction integral have been calculated by a fast algorithm using the fast Fourier transform (FFT).Meanwhile, the applicable range for the algorithm has been presented. By computer simulation, the results have shown that the algorithm has advantages of high reliability and high effectiveness.
