Title: An Algorithm for Fresnel Diffraction Computing Based on Fractional Fourier Transform
Authors: Stoilov, Georgi
Keywords: Fresnel diffraction,
fractional Fourier-transform

Abstract: The fractional Fourier transform (FrFT) is used for the solution of the diffraction integral in optics. A scanning approach is proposed for finding the optimal FrFT order. In this way, the process of diffraction computing is speeded up. The basic algorithm and the intermediate results at each stage are demonstrated.
