The Laguerre-Gaussian series representation of two-dimensional fractional Fourier transform
J. Phys. A: Math. Gen. 31(1998)9353-9357. Printed in the UK，-0001，（）：
In this paper the Laguerre-Gaussian (LG) series representation of the twodimensional fractional Fourier transform is derived from conventional ordinary Fourier transform in polar coordinates. The kernel of this series representation is constituted by Laguerre-Gaussian functions, from which the series representation of a fractional Hankel transform can be easily derived. The connection between the gradient-index medium and the LG series representation is illustrated as an example of its applications.
