Components of purity of a Mueller matrix

Journal of the Optical Society of America A, 2011
The degree of polarimetric purity of a Mueller matrix, also called "depolarization index" [Opt. Acta 33, 185 (1986)] is expressed as a quadratic average of two contributions of different nature. The contribution due to the polarizance and diattenuation properties is given by a unique parameter called "degree of polarizance," and the complementary ...

Differential Mueller matrix of a depolarizing homogeneous medium and its relation to the Mueller matrix logarithm

Journal of the Optical Society of America A, 2015
The different z-dependence and non-commutativity of the two components of the differential Mueller matrix of a homogeneous depolarizing medium prevent its formal identification with the Mueller matrix logarithm. By using a classic linear differential equation expansion, we advance a procedure for the extraction of the elementary polarization properties,

Mueller-matrix characterization of liquid crystals

Thin Solid Films, 2004
Abstract Generalized spectroscopic ellipsometry (g-SE) has been applied to many anisotropic materials. This measurement is based on the 2×2 Jones matrix sample representation, which is often sufficient. However, when the reflected or transmitted light becomes sufficiently depolarized, the Mueller-matrix (MM) representation may be required for ...

Measurement of the Mueller matrix for ocean water

Applied Optics, 1984
The normalized light scattering polarization matrix has been measured for ocean water using an electrooptic light scattering polarimeter. Measurements were done on samples from the Atlantic and Pacific Oceans and the Gulf of Mexico. The polarization effects in the matrices were found to have, in general, a form which is similar to polarization effects ...

Mueller matrix roots depolarization parameters

Applied Optics, 2012
The Mueller matrix roots decomposition recently proposed by Chipman in [1] and its three associated families of depolarization (amplitude depolarization, phase depolarization, and diagonal depolarization) are explored. Degree of polarization maps are used to differentiate among the three families and demonstrate the unity between phase and diagonal ...

Optimization of a snapshot Mueller matrix polarimeter

Optics Letters, 2008
We report on the optimization of a snapshot Mueller matrix polarimeter performed by using singular-value decomposition. The snapshot technique relies on wavelength polarization coding by four wave plates. The statistical noise on Mueller components is minimized through adjustment of the thickness of each plate.

Mueller matrix analysis of infrared ellipsometry

Applied Optics, 1994
A Mueller analysis has been done of IR ellipsometry performed with imperfect optical components. Equations linking experimental and calculated Fourier coefficients have been derived and consistently solved. Correction routines for permittivity measurements are demonstrated and discussed with gold and SrTiO(3) as examples.

Least-squares analysis of the Mueller matrix

Optics Letters, 2006
In a single-mode fiber excited by light with a fixed polarization state, the output polarizations obtained at two different optical frequencies are related by a Mueller matrix. We examine least-squares procedures for estimating this matrix from repeated measurements of the output Stokes vector for a random set of input polarization states.

Expressions for parallel decomposition of the Mueller matrix

Journal of the Optical Society of America A, 2016
It is useful to convert between the Mueller matrix and two different Hermitian matrices, representing an optical material or system. We introduce forms for the matrices for transforming between the column vector forms of these different matrices. A review of matrix algebra is presented.

Structure of a general pure Mueller matrix

Applied Optics, 1994
Changes in the radiance and state of polarization of a beam of radiation can often be described by means of a pure Mueller matrix. Such a 4 × 4 matrix transforms Stokes parameters and can be expressed in terms of the elements of a 2 × 2 Jones matrix. Relations between the two types of matrix are discussed.
