The method originally proposed by Siegman [Opt. Lett. 1, 13 (1977)] for evaluating numerically, the Hankel transform by fast-Fourier-transform techniques is reconsidered. A novel analytical form is found that permits a numerical computation of the Hankel transform with accuracy comparable to that of Siegman's approach without lower-end corrections; but for simplicity and numerical efficiency the original approach remains unsurpassed.
