THE CONE OF THE MUELLER MATRICES

, 2023
In the study of polarized light, there are two basic notions: the Stokes vectors and the matrices which preserve them, called Mueller matrices. The set of Stokes vectors forms a cone: the Future Light Cone. In this work we will see that the Mueller matrices also form a cone in the vector space of real matrices of size 4X4, called the Mueller Cone.

Polarimetric subtraction of Mueller matrices

Journal of the Optical Society of America A: Optics and Image Science, and Vision, 2013
A general formulation of the additive composition and decomposition of Mueller matrices is presented, which is expressed in adequate terms for properly performing the "polarimetric subtraction," from a given depolarizing Mueller matrix M, of the Mueller matrix of a given nondepolarizing component that is incoherently embedded in the whole system ...

Characteristic properties of Mueller matrices

Journal of the Optical Society of America A: Optics and Image Science, and Vision, 2000
A complete and minimum set of necessary and sufficient conditions for a real 4 x 4 matrix to be a physical Mueller matrix is obtained. An additional condition is presented to complete the set of known conditions, namely, the four conditions obtained from the nonnegativity of the eigenvalues of the Hermitian matrix H associated with a Mueller matrix M ...

Alternative depolarization criteria for Mueller matrices

Journal of the Optical Society of America A: Optics and Image Science, and Vision, 2010
It is shown that the currently used depolarization criteria of Gil and Bernabeu [Opt. Acta 33, 185 (1986)] and Cloude [Optik (Stuttgart) 75, 26 (1986)] may produce erroneous results when applied to a special class of Mueller matrices. Alternative criteria, based on the Lorentz singular values of the Mueller matrix, are proposed.

Poincaré sphere mapping by Mueller matrices

Journal of the Optical Society of America A: Optics and Image Science, and Vision, 2013
By using the symmetric serial decomposition of a normalized Mueller matrix M [J. Opt. Soc. Am. A 26, 1109 (2009)] as a starting point and by considering the reciprocity property of Mueller matrices, the geometrical features of the Poincaré sphere mapping by M are analyzed in order to obtain a new parameterization of M in which the 15 representative ...

Explicit algebraic characterization of Mueller matrices

Optics Letters, 2014
A general explicit algebraic characterization of Mueller matrices is presented in terms of the non-negativity of a set of leading principal minors of the coherency matrix C(A) associated with the arrow form M(A) of a given Mueller matrix M. This result is also formulated through a set of four characteristic Stokes vectors.

Mueller and Kennaugh matrices in radar polarimetry

IEEE Transactions on Geoscience and Remote Sensing, 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. Although these two matrices are quite similar, there exists a basic difference between them that seems to have been overlooked by a number of researchers, resulting in a great deal of ...

Mueller matrices in fluorescence scattering

Optics Letters, 2012
A reappraisal of the 1929 analysis of luminescence by Soleillet reveals the form of the Mueller matrix for fluorescence scattering whose parameters are directly defined in terms of the now-familiar fluorescence anisotropy parameter. If the scattering analyte is optically active, it is further shown how fluorescence detected circular dichroism and ...
