In wiki (http://en.wikipedia.org/wiki/Fourier_transform), there said the fourier transform of the Bessel function (zeroth order J0) is a rect function (window). But I also saw a text (about optics) that the Fourier transform on a ring slit (or ring disk) is zeroth-order Bessel function, so which one is correct? If wiki is correct, what is the fourier transform on a ring disk?(adsbygoogle = window.adsbygoogle || []).push({});
