Abstract
The method originally proposed by Siegman [Opt. Lett. 1, 13 (1977)] fo r evaluating numerically the Hankel transform by fast-Fourier-transfor m techniques is reconsidered. A novel analytical form is found that pe rmits a numerical computation of the Hankel transform with accuracy co mparable with that of Siegman's approach without lower-end corrections ; but for simplicity and numerical efficiency the original approach re mains unsurpassed.
