| Abstract: | The diffraction-free beam produced by an axicon has constant size and intensitydistributions. Therefore it could be exploited for practical use in many areas. Thediffraction-free beam and its properties were introduced in this paper.Finally,the designingmethod of a binary axicon and computer based simulation results are presented. |
