| Abstract: | Based on the diffraction theory and stationary phase method, the diffraction patterns produced behind an axicon illuminated by spherical wave are derived. The calculating formula and simulation results of the patterns are given. The simulation results are compared with those obtained when the axicon is illuminated with a collimated light beam. The conclusions drawn are presented. |
