Polarimeters for the Detection of Anisotropy from Reflectance [PDF]

open access: yesMicromachines
Polarimetry is used to determine the Stokes parameters of a laser beam. Once all four S0,1,2,3 parameters are determined, the state of polarisation is established.

Application of Microwave Polarimetry to the Characterization of Fiber Misalignment in Composites

open access: yesIEEE Open Journal of Instrumentation and Measurement, 2022
In this paper synthetic aperture radar (SAR) polarimetry techniques are applied to detect and characterize fiber misalignment in both carbon fiber sheets and glass fiber reinforced polymer (GFRP) composites. The principle behind SAR polarimetry technique

Mueller Matrix Microscopy for In Vivo Scar Tissue Diagnostics and Treatment Evaluation

open access: yesSensors, 2022
Scars usually do not show strong contrast under standard skin examination relying on dermoscopes. They usually develop after skin injury when the body repairs the damaged tissue.

Experimental obtaining of polarization ghost images by ghost polarimetry [PDF]

open access: yesEPJ Web of Conferences, 2019
The paper presents the experimental implementation of a new version of the ghost image method ghost polarimetry in unpolarized light. Like conventional polarimetry, ghost polarimetry is used to study the polarization properties of objects.

Analytical and numerical modeling of optical second harmonic generation in anisotropic crystals using ♯SHAARP package

open access: yesnpj Computational Materials, 2022
Electric-dipole optical second harmonic generation (SHG) is a second-order nonlinear process that is widely used as a sensitive probe to detect broken inversion symmetry and local polar order.

Compton Polarimetry

open access: yes, 2022
Photons preferentially Compton scatter perpendicular to the plane of polarisation. This property can be exploited to design instruments to measure the linear polarisation of hard X-rays ($\sim$10 - 100 keV). Photons may undergo two interactions in the sensitive volume of the instrument, i.e. a scattering followed by an absorption.

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 ...

Design of Full Stokes Vector Polarimetry Based on Metasurfaces for Wide-Angle Incident Light

open access: yesPhotonics, 2023
Polarization measurement plays an important role in optical detection, communication, and imaging systems. Compact polarimetry with a wide angle of incident light will break the restrictions of the limited incident angle and improve its practicality.
