Abstract The classical Mach–Zehnder two-beam set-up has been modernized with the use
of polarization elements to generate a set of optical vortices. The main element of these set …

We present some applications of the optical vortex birefringence compensator, based on the
C polarization type singularities generated using two Wollaston compensators. The theory …

A new application of the optical vortex birefringence compensator has been presented. Two
parameters of elliptically birefringent medium, an ellipticity angle and an optical path …

What we believe to be a new arrangement of an optical vortex interferometer (OVI) is
presented. In the proposed configuration the optical vortex lattice is generated in a one …

We present an application of the optical vortex interferometer (OVI). The OVI is based on a
regular net of optical vortices that are generated by the interference of three plane waves. If …

In recent years a lot of effort was put into testing and improving the idea of a three beam
interferometer known as Optical Vortices Interferometer (OVI). Devices based on the idea of …

A classical Mach-Zehnder two-beam interferometer was modernized using the Wollaston
compensator, which allowed obtaining a stable set of specific optical markers--optical …

The application of the optical vortex interferometer (OVI) to small-angle rotation
measurements is presented. The OVI is based on a regular lattice of optical vortices. In our …

Different interferogram demodulation methods of optical vortex interferometer (OVI) have
been proposed over the last two decades aiming at dynamic phase measurement. Taking …

We propose a novel birefringent interferometer setup for the study of unfolding points, and
obtain for the first time to our knowledge the spatial polarization structure very near the …
