Abstract

This work is devoted to a theoretical study of the ABCD-Hankel transformation. As the frequency-domain is very important in optics, we investigate a novel general Collins formula in two dimensions with polar coordinates. We also investigate the direct relationship between input and output spatial frequency spectra of a light field in this frame system in the case of a Fourier, Fresnel and fractional Fourier (FRT) transformations for two families of beams: Bessel-Gaussian and Bessel-modulated Gaussian beams.

Keywords: ABCD-Hankel; Transformation; Collins Formula; Fourier; Fresnel; Fractional Fourier.
