An analysis of an optical vortices interferometer with focused beam
optical vortex interferometry
2011/5/6
In recent years a lot of effort was put into testing and improving the idea of a three-beam interferometer known as an optical vortices interferometer (OVI). Devices based on the idea of the OVI allow...
The interferometry based on regular lattice of optical vortices
optical vortex vortex lattice

The optical vortices are point phase dislocations. The point where the phase is undetermined is called a vortex point. The lattice of optical vortices can be generated by the interference of three or ...

An on-axis computer-synthesized hologram-based technique is introduced to create white-light “rainbow” optical vortices, which are stable with respect to environmental disturbances under long-distance...
