On the algebraic characterization of a Mueller matrix in polarization optics - I. Identifying a mueller matrix from its N matrix [PDF]

open access: yes, 1998
We revisit the problem of identifying a Mueller matrix M through its N matrix N = (M) over tilde GM where G is the familiar Minkowski matrix diag (1, -1, -1, -1) and the tilde denotes matrix transposition.

Stokes Dynamic Polarimeter for Non-Organic and Organic Samples Characterization

open access: yesSensors, 2022
The light polarization properties provide relevant information about linear–optical media quality and condition. The Stokes–Mueller formalism is commonly used to represent the polarization properties of the incident light over sample tests.

Extended Representation of Mueller Matrices

open access: yesPhotonics, 2023
The so-called arbitrary decomposition of a given Mueller matrix into a convex sum of nondepolarizing constituents provides a general framework for parallel decompositions of polarimetric interactions.

A Characterization Method of Thin Film Parameters Based on Adaptive Differential Evolution Algorithm

open access: yesIEEE Access, 2021
According to the transmission mode of polarized light in Mueller ellipsometry, a characterization method for the thickness and optical constants of isotropic nano films based on Self-Adaptive Differential Evolution algorithm (SADE) is proposed.

Physical Significance of the Determinant of a Mueller Matrix

open access: yesPhotonics, 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 physical and geometric significance of the determinant of M (detM) requires a specific analysis, performed ...

Mueller Matrix Polarimetry on Cyanine Dye J-Aggregates

open access: yesMolecules, 2023
Cyanine dyes are known to form H- and J-aggregates in aqueous solutions. Here we show that the cyanine dye, S0271, assembles in water into vortex induced chiral J-aggregates.

Physics-based rendering: Simulated Mueller matrix imaging [PDF]

open access: yes, 2022
Physics-based rendering (PBR) engines attempt to generate photorealistic images by mimicking light-matter interaction in a physically plausible way. PBR has become the standard rendering method in the fields of animation, gaming, and computer graphics ...
