Abstract

This article explores the possibility of improving the detection of spatial anisotropy and visualization of weak wave aberrations when the lens is supplemented with a diffractive axicon. Fresnel transforms are used to simulate the formation of intensity distributions at different distances from the input plane. The results of numerical simulation of diffraction by a composite element (lens and axicon) under illumination by an aberrated wavefront are presented. A significant increase in the efficiency of visualization of weak wave aberrations is shown when using the proposed method based on the deviation of the intensity pattern for an aberrated and ideal wavefront.
