Short-wave infrared Mueller matrices and polarization parameters for in vivo skin surface reflectance

open access: yes, 2018
Short-wave infrared light is weakly absorbed by human epidermal and dermal tissue. Investigation of polarization characteristics of human skin taken in vivo distinguishes how depolarization index and the Mueller matrix are markers that can identify skin ...

Quantum theory of polarimetry: From quantum operations to Mueller matrices

open access: yesPhysical Review Research, 2020
Quantum descriptions of polarization show the rich degrees of freedom underlying classical light. While changes in polarization of light are well described classically, a full quantum description of polarimetry, which characterizes substances by their ...

Mueller matrix characterization of porous media in visible

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2011
In this paper, we apply Mueller polarimetry to study different samples of porous media compacted as tablets from a pharmaceutical excipient microcrystalline cellulose. We measured the Mueller matrices of the samples with the home made polarimeter using a

Mueller polarimetric imaging for fast macroscopic mapping of microscopic collagen matrix remodeling by smooth muscle cells

open access: yesScientific Reports, 2021
Smooth muscle cells (SMCs) are critical players in cardiovascular disease development and undergo complex phenotype switching during disease progression. However, SMC phenotype is difficult to assess and track in co-culture studies.

Assessment of the Impact of Nanowarming on Microstructure of Cryopreserved Fibroblast-Containing 3D Tissue Models Using Mueller Polarimetry

open access: yesPhotonics, 2023
We studied the impact of two different thawing mechanisms on the microstructure of defrosted cryopreserved 3D tissue models using transmission Mueller microscopy and a statistical analysis of polarimetric images of thin histological sections of defrosted

Polar decomposition of Mueller matrices for 2D-structured surfaces

open access: yesEPJ Web of Conferences, 2010
In this research, the Polar Decomposition (PD) has been applied to the Mueller matrices (MMs) of the light scattered by linear ribs of rectangular profile on a flat substrate.

Analyzing the Influence of Imaging Resolution on Polarization Properties of Scattering Media Obtained From Mueller Matrix

open access: yesFrontiers in Chemistry, 2022
The Mueller matrix contains abundant micro- and even nanostructural information of media. Especially, it can be used as a powerful tool to characterize anisotropic structures quantitatively, such as the particle size, density, and orientation information

Characterization of Mueller matrices in polarization optics

open access: yes, 1992
We derive the necessary and sufficient conditions that a real 4×4 matrix should satisfy in order that it qualifies to be the Mueller matrix of some linear system.
