Modeling the image obtained by a system of vortex harmonic lenses

Abstract

Abstract The possibility of obtaining images using a system based on vortex diffraction lenses is considered. A system of two vortex harmonic lenses was simulated. In the system the total intensity distribution was calculated using the Fresnel transform. The width of the point spread function, which is 66 μm, is obtained. The influence of spatial filters on the result of this system is considered.
