Abstract

An optical vortex interferometry model based on Kummer beams with an integer topological charge is presented. The proposed approach makes it possible to improve the stage of extracting data on the phase shift of the object beam introduced by an investigated object directly via detecting the angular positions of local minima of the intensity of a field of superposition of Kummer and Gaussian beams with different amplitude ratios.
