Using a dynamic Mueller matrix in modeling of retinal birefringence scanning systems

open access: yesResults in Optics, 2023
Polarization modeling by means of the Mueller matrix formalism is widely used for representation and optimization of the performance of complex polarization-sensitive systems. Yet, this turns out to be a challenge, as soon as such systems become dynamic,

Hydrosol Scattering Matrix Inversion Across a Fresnel Boundary

open access: yesFrontiers in Remote Sensing, 2022
We exhibit a proof-of-concept laboratory study for inversion of the partial Mueller scattering matrix of hydrosols from polarimetric observations across a smooth Fresnel boundary.

Point Source C-band Mueller Matrices for the Green Bank Telescope

open access: yesThe Astronomical Journal, 2023
C -band Mueller matrices for the Green Bank Telescope are presented here which enable on-sky Stokes parameters for point sources at the beam center to be determined. Standard calibrators, 3C 138 and 3C 286, were observed using the Spider program to steer

Multichannel Polarization Lidar Measurements of Aerosols and Cirrus Clouds [PDF]

open access: yesEPJ Web of Conferences, 2020
In this paper we report using a 6-channel polarization detector to measure optical properties of aerosols and clouds. The polarization lidar system is designed to measure Stokes vectors and Mueller matrices from back-scatterings of air, aerosols and ...

Optimal Measurement Matrix of Partial Polarimeter for Measuring Ellipsometric Parameters With Eight Intensity Measurements

open access: yesIEEE Access, 2019
We demonstrate that the ellipsometric parameters of the isotropic samples can be measured by a partial polarimeter with only eight intensity measurements.

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

Characterization of porous media based on the polarimetric matrix models

open access: yesJournal of Biomedical Photonics & Engineering, 2017
In this paper, we measured the Mueller matrices of the samples with different porosity in the visible range (the wavelength of the input radiation ) for the observation angles from  to .
