Interferometric methods in diagnostics of polarization singularities
TLDR
In this paper, an interferometric technique for analysis of a polarization singular skeleton (s contours and C points) of an optical vector field is elaborated, and complete characteristics of C points and s contours may be reconstructed from interferometrical data.Abstract:
An interferometric technique for analysis of a polarization singular skeleton (s contours and C points) of an optical vector field is elaborated. It was shown that complete characteristics of C points and s contours may be reconstructed from interferometric data. Some examples of elaborated interferometric technique application to the analysis of randomly polarized speckle-fields singularities are presented.read more

Polarization singularities in paraxial vector fields: morphology and statistics
TL;DR: In this article, the geometry of ellipse fields at these singularities, using the Stokes parameters and others to characterize the singular geometry and morphology, was investigated, and the densities and correlations of the different types of polarization singularities were calculated in random polarization fields, and compared to the statistics of phase singularities and random surfaces.

The optical singularities of birefringent dichroic chiral crystals
Michael V Berry,Mark R. Dennis +1 more
TL;DR: In this article, explicit formulae are obtained for the two refractive indices and polarizations in optically anisotropic crystals that are both dichroic (absorbing) and chiral (optically active).

Stokes singularity relations
TL;DR: Six independent relationships are obtained that connect the topological charges of these singularities on special closed contours with the charges of singularities that are enclosed by these contours that imply topological polarization correlations of an infinite range.

Optical polarization singularities and elliptic stationary points.
TL;DR: Detailed, high-resolution experimental data confirm with high precision the elliptic-field topological sign rule, loop rules, and Stokes singularity relations introduced recently.

Polarization manifestations of correlation (intrinsic coherence) of optical fields
TL;DR: It is substantiated that the experimental estimation of the level of intrinsic coherence of statistical vector optical fields must include not only the measurement of the visibility of the interference pattern but also the degree of polarization in the resulting spatial distribution of a field.
