Abstract

We proposed an experimental method for determining the localization of phase field singularities. The method consists in measuring the correlation functions of the field and intensity for local fields by several pixels, calculating the ratio of their correlation radii and pixel-by-pixel binding of these parameters to the entire field. Computer simulations and experimental studies have shown that for practically all developed speckle fields, the ratio of the correlation radii saturates in the far detection zone at a value of about 0.64–0.7.
