Polarization gating based on Mueller matrices [PDF]
Journal of Biomedical Optics, 2017 We present mathematical formulas generalizing polarization gating (PG) techniques. PG refers to a collection of imaging methods based on the combination of different controlled polarization channels. In particular, we show how using the measured Mueller matrix (MM) of a sample, a widespread number of PG configurations can be evaluated just from ...

Thermodynamic Reversibility in Polarimetry
Photonics, 2022 The action of linear media on incident polarized electromagnetic waves can produce two kinds of thermodynamic irreversible effects, namely, loss of intensity, in general anisotropic, and reduction of the degree of polarization. Even though both phenomena

Exploring the Polarization of Light in Ferrofluids with Mueller Matrices
Magnetochemistry, 2022 We studied the polarization of light in a thin film of ferrofluid subjected to a magnetic field using the Mueller matrix formalism. By observing the results of some experiments, we relate the observed light patterns with Stokes vectors that can be ...
