Mueller-Polarimetry of Barley Leaves I: Depolarization Metrics

open access: yesPhotonics, 2023
In this paper, Mueller polarimetry is applied to study the three groups of common barley leaf samples (Hordeum vulgare) in the visible spectrum (λ = 632.8 nm): Chlorina mutant, Chlorina etiolated mutant and Cesaer varieties.

Mueller coherency matrix method for contrast image in tissue polarimetry [PDF]

open access: yesSPIE Proceedings, 2007
In this work, we propose the use of the Mueller Coherency matrix of biological tissues in order to increase the information from tissue images and so their contrast. This method involves different Mueller Coherency matrix based parameters, like the eigenvalues analysis, the entropy factor calculation, polarization components crosstalks, linear and ...

Mueller matrix polarimetry using full Poincaré beams

open access: yesOptics and Lasers in Engineering, 2019
Full Poincaré beams (FPBs) are proposed for polarimetric applications. Such beams present all states of totally polarized light across their transverse section at once and therefore can be considered as parallel polarization state generators. A simple setup, including a FPB as input light, has been designed and implemented to measure the Mueller matrix

Full-Field Stokes–Mueller Matrix Imaging Polarimetry System Based on Electro-Optical Modulators

open access: yesIEEE Photonics Journal, 2018
A new full-field Stokes–Mueller polarimetry system with no moving parts is proposed for imaging the Mueller matrix of optical samples. The polarization state generator (PSG) of the proposed system contains two electro-optical (EO) modulators to ...

Three-Dimensional Nonlinear Stokes - Mueller Polarimetry

open access: yes, 2018
The formalism is developed for a tree-dimensional ($3D$) nonlinear Stokes-Mueller polarimetry. The expressions are derived for the generalized $3D$ linear and nonlinear Stokes vectors, and the corresponding nonlinear Mueller matrix.
