Stress Detection of Conical Frustum Windows in Submersibles Based on Polarization Imaging

open access: yesSensors, 2022
Stress detection of the conical frustum window is a very important issue to ensure the safety of deep manned submersibles. In this paper, we propose a method based on polarization imaging to evaluate the stress accumulation and recovery in the conical ...

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.

Preservation of Historically and Scientifically Important Geospatial Data From Venus

open access: yesEarth and Space Science, Volume 13, Issue 3, March 2026.
Abstract A large volume of scientifically and historically important data from the early exploration of Venus is not widely available to researchers. Our work is focused on ameliorating this problem with the archival of geospatial data including radar, topography, and radiometry.

Mueller and Kennaugh Matrices in Radar Polarimetry

open access: yes, 1994
This paper is concerned with the notions of the Mueller matrix and the Kennaugh (or Stokes scattering) matrix, that are commonly used in the field of radar polarimetry.

Polarized Light Backscattering From Turbid Media: Why Do Rayleigh Scatterers Preserve Linear Polarization More Than Circular Polarization?

open access: yesLaser &Photonics Reviews, Volume 20, Issue 4, 19 February 2026.
Turbid media containing small‐sized Rayleigh‐regime scatterers present a ‘special case’ in which linearly polarized light is found to be less depolarized than circularly polarized light. The underlying mechanisms that give rise to this phenomenon are not yet understood.

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.

Inverse problem of Mueller polarimetry for metrological applications

open access: yes, 2021
International audienceAbstract Inverse problem of Mueller polarimetry is defined as a determination of geometrical features of the metrological structures (i.e. 1D diffraction gratings) from its experimental Mueller polarimetric signature. This nonlinear

Structure‐Response Relationships in Rigid C2‐Symmetric Excitonic Systems: Principles, Modulation, and Functional Design Strategies

open access: yesChemPhysChem, Volume 27, Issue 2, January 2026.
Rigid C2‐symmetric chromophores reveal how transition dipole orientation, magnitude, and conformational locking govern exciton coupling and g‐factor amplification, providing a structural blueprint for the rational design of advanced chiroptical molecular and material architectures.

Mueller matrix polarimetry for differentiating characteristic features of cancerous tissues

open access: yesJournal of Biomedical Optics, 2014
Polarization measurements allow one to enhance the imaging contrast of superficial tissues and obtain new polarization sensitive parameters for better descriptions of the micro- and macro- structural and optical properties of complex tissues. Since the majority of cancers originate in the epithelial layer, probing the morphological and pathological ...
