Thermodynamic Reversibility in Polarimetry

open access: yesPhotonics, 2022
The action of linear media on incident polarized electromagnetic waves can produce two kinds of thermodynamic irreversible effects, namely, loss of intensity, in general anisotropic, and reduction of the degree of polarization. Even though both phenomena

Anisotropic integral decomposition of depolarizing Mueller matrices [PDF]

open access: yes, 2019
We propose a novel, computationally efficient integral decomposition of depolarizing Mueller matrices allowing for the obtainment of a nondepolarizing estimate, as well as for the determination of the elementary polarization properties, in terms of mean ...

Characterization of Mueller matrices in retroreflexellipsometry [PDF]

open access: yes, 2021
Ellipsometry is a widely-used technique for characterizing materials and thinfilms. The principle is based on the polarization changes after light is reflectedor transmitted at a sample.

The effect of relative humidity on the polarization Mueller matrix under the oil smoke environment

open access: yesFrontiers in Physics, 2023
For the variation of the polarized Mueller matrix of oil smoke particles under different relative humidity levels, the polarized single scattering characteristics of oil smoke particles are studied by using the Mie scattering theory, and the multiple ...

Monochromatic Depolarizer Based on Liquid Crystal

open access: yesCrystals, 2019
Polarization is a very useful parameter of a light beam in many optical measurements. Improvement of holographic systems requires optical elements which need a diffused and depolarized light beam.
