The optical vortex interferometry theory, technology, and applications

摘要

The regular net of optical vortices generated by the interference of three plane waves can be used for optical measurements. The instrument based on such vortex net is called optical vortex interferometer. In this paper the special properties of optical field generated by the interference of three plane waves are described. The technological issues of the optical vortex interferometer are also discussed. Finally, two examples of application of the optical vortex interferometer in context of the special properties of the interference field generated by three plane waves, are presented.
