摘要：
Optical vortices interferometry (OVI) uses a regular vortices net generated by three plane waves interference as a reference system for phase evaluation. This paper introduces new methods for vortex points localization, which is of primary importance for OVI. The methods are tested both oil the computer generated and oil the experimental interferograms. The corresponding computer algorithms are fast and easy for implementation. Localization accuracy is high enough to enable valuable measurements with OVI. (C) 2004 Elsevier B.V. All rights reserved.
