Three-Dimensional Nonlinear Stokes - Mueller Polarimetry [PDF]

, 2019
The formalism is developed for a tree-dimensional ($3D$) nonlinear Stokes-Mueller polarimetry. The expressions are derived for the generalized $3D$ linear and nonlinear Stokes vectors, and the corresponding nonlinear Mueller matrix.

Spatially Addressable Polarimetric Calibration of Reflective-Type Spatial Light Modulator Using Mueller–Stokes Polarimetry

Frontiers in Physics, 2021
Mueller–Stokes polarimetry is emerging as a prominent noninvasive imaging technique to study the structural characteristics of an anisotropic medium. Spatial light modulator (SLM) is a programmable liquid crystal device (LCD), which is used to modulate ...

Synthesis, Structure, and Thin Film Optical Properties of a Chiral Benzothiazole-Derived Squaraine. [PDF]

Chemphyschem
Solution‐processed thin films can be sensitive to the choice of solvent and thermal annealing, which we explore for a chiral benzothiazole squaraine. We observe peculiarly shaped excitonic circular dichroism in uniaxially anisotropic thin films, in which the presumed Davydov bands are spatially distributed exclusively into in‐plane (UDC) and out‐of ...

Experimental Mueller matrix polarimetry with full Poincaré beams and a CCD camera [PDF]

EPJ Web of Conferences, 2021
Recently, the use of full Poincaré beams for extracting the Mueller matrix of a sample has been proposed. These beams present all possible polarization states across their transverse section.

Polarimetric approach for well-defined impurities detection in isotropic materials [PDF]

Journal of the European Optical Society-Rapid Publications, 2014
In this paper, a new kind of approach to reveal the presence of well-defined impurities in isotropic materials is proposed and verified against actual measurements over real samples. The rationale lies in the different polarimetric symmetry properties of

Physical Significance of the Determinant of a Mueller Matrix

Photonics, 2022
The determinant of a Mueller matrix M plays an important role in both polarization algebra and the interpretation of polarimetric measurements. While certain physical quantities encoded in M admit a direct interpretation, the understanding of the ...
