Abstract

The vortex lattice can be practically used in metrology. The Optical Vortex Interferometer (OVI) is an useful tool to generate a regular lattice of optical vortices. Unfortunately, there are still many problems that have to be solved before an OVI-based device can go into production. In this paper experimental results of using another type of OVI, OVI with one focused beam, are presented. The results of measuring small displacements of reflecting areas are also shown.
