Maximum-likelihood estimation prevents unphysical Mueller matrices [PDF]

open access: yesOptics Letters, 2005
We show that the method of maximum-likelihood estimation, recently introduced in the context of quantum process tomography, can be applied to the determination of Mueller matrices characterizing the polarization properties of classical optical systems ...

Extended Representation of Mueller Matrices

open access: yesPhotonics, 2023
The so-called arbitrary decomposition of a given Mueller matrix into a convex sum of nondepolarizing constituents provides a general framework for parallel decompositions of polarimetric interactions.

Optical Chirality Determined from Mueller Matrices [PDF]

open access: yesApplied Sciences, 2021
Optical chirality, in terms of circular birefringence and circular dichroism, is described by its electromagnetic and magnetoelectric material tensors, and the corresponding optical activity contributes to the Mueller matrix.

Design of Partial Mueller-Matrix Polarimeters for Application-Specific Sensors [PDF]

open access: yesSensors
At a particular frequency, most materials and objects of interest exhibit a polarization signature, or Mueller matrix, of limited dimensionality, with many matrix elements either negligibly small or redundant due to symmetry.

Polar Decomposition of Jones Matrix and Mueller Matrix of Coherent Rayleigh Backscattering in Single-Mode Fibers [PDF]

open access: yesSensors
The Jones matrix and the Mueller matrix of the coherent Rayleigh backscattering (RB) in single-mode fibers (SMFs) have been derived recently. It has been shown that both matrices depict two polarization effects—birefringence and polarization-dependent ...

Synthetic Mueller Imaging Polarimetry

open access: yesPhotonics, 2023
The transformation of the state of polarization of a light beam via its linear interaction with a material medium can be modeled through the Stokes–Mueller formalism.

Singular Mueller matrices [PDF]

open access: yesJournal of the Optical Society of America A, 2016
Singular Mueller matrices play an important role in polarization algebra and have peculiar properties that stem from the fact that either the medium exhibits maximum diattenuation and/or polarizance, or because its associated canonical depolarizer has the property of fully randomizing, the circular component (at least) of the states of polarization of ...

Loops and polarization in strong-field QED

open access: yesNew Journal of Physics, 2021
In a previous paper we showed how higher-order strong-field-QED processes in long laser pulses can be approximated by multiplying sequences of ‘strong-field Mueller matrices’.

Depolarizing differential Mueller matrices [PDF]

open access: yesOptics Letters, 2011
The evolution of a polarized beam can be described by the differential formulation of Mueller calculus. The nondepolarizing differential Mueller matrices are well known. However, they only account for 7 out of the 16 independent parameters that are necessary to model a general anisotropic depolarizing medium.
