Optimization of instrument matrix for Mueller matrix ellipsometry based on partial elements analysis of the Mueller matrix

open access: yesOptics Express, 2017
We consider the Mueller matrix ellipsometry (MME) measuring the ellipsometric parameters of the isotropic sample and the anisotropic sample under certain conditions in the presence of either Gaussian additive noise or Poisson shot noise. In this case, the ellipsometric parameters only relate to partial elements in Mueller matrix, and we optimize the ...

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.

Mueller quaternion with matrix coefficients for depolarizing and nondepolarizing media

open access: yes, 2020
It is shown that a Mueller quaternion can be formulated as a quaternion with matrix coefficients, and this Mueller quaternion transforms the Stokes quaternion for depolarizing process as well as for nondepolarizing process. Mueller quaternion keeps track

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.

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 ...
