Characterization of the Mueller Matrix: Purity Space and Reflectance Imaging

open access: yesPhotonics, 2022
Depolarization has been found to be a useful contrast mechanism in biological and medical imaging. The Mueller matrix can be used to describe polarization effects of a depolarizing material. An historical review of relevant polarization algebra, measures

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,

A Table of Some Coherency Matrices, Coherency Matrix Factors, and Their Respective Mueller Matrices

open access: yesPhotonics, 2022
Many books on polarization give tables of Mueller matrices. The coherency matrix has been found useful for interpretetion of the Mueller matrix. Here we give a table of Mueller matrices M, coherency matrices C, and coherency matrix factors F for ...

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

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.

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 ...

The influence of cell window imperfections on the calibration and measured data of two types of rotating-analyzer ellipsometers [PDF]

open access: yes, 1980
A graphical method has been developed to determine the plane of incidence in the presence of cell windows with small retardation. For two types of rotating-analyzer ellipsometers, expressions have been derived that relate the experimental parameters and ...
