Analysis of Accuracy of Optical Vortex Detection Algorithms

Abstract

Application of four algorithms developed for detecting optical vortices in model problems of singular optics is considered. Computational schemes that should be constructed for the software implementation of the algorithms are presented and the input information required for the operation of the computer applications is specified. Special attention is paid to the accuracy in detecting the number and coordinates of singular points of a wavefront. Depending on the characteristic of the methods and input data volume, the areas of their possible use (experiments or purely numerical simulation) are determined.
