Abstract: Starting from the imaging properties,the imaging transformation properties of the semi concave axicon is theoretically analyzed.Also the intensity distribution of the output beam is numerically calculated.The calculation has proved that the beam transformation through a semi concave axicon has the characteristics called "approximate diffraction-free beam".
