Diffraction of Bessel beams on 2D amplitude gratings -- a new branch in the Talbot effect study

I. A. Kotelnikov, O. E. Kameshkov, B. A. Knyazev

In this paper, an analytical theory for the diffraction of a Bessel beam of arbitrary order $J_l(\kappa r)$ on a 2D amplitude grating is presented. The diffraction pattern in the main an…
