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.

Back-focal plane Mueller matrix microscopy: Mueller conoscopy and Mueller diffractrometry

Applied Surface Science, 2017
Abstract The common mode of observation in an imaging Mueller matrix polarimeter is orthoscopic observation, where the front focal plane of the objective is focused onto the camera sensor. Different points on the camera sensor correspond to different points on the sample.

Geometry of the Mueller matrix spectral decomposition

Journal of the Optical Society of America A, 2016
An arbitrary Mueller matrix can be decomposed into a sum of up to four deterministic Mueller-Jones matrices, with strengths given by the eigenvalues of an associated Hermitian matrix. A geometrical representation of the eigenvalues in terms of the matrix invariants, using a barycentric (quaternary) plot, is presented.

Mueller matrix of a dicot leaf

SPIE Proceedings, 2012
A better understanding of the information contained in the spectral, polarized bidirectional reflectance and transmittance of leaves may lead to improved techniques for identifying plant species in remotely sensed imagery as well as better estimates of plant moisture and nutritional status.

Mueller matrix by imaging polarimeter

SPIE Proceedings, 2012
Most of imaging polarimeters in the field measure only a few components of the Mueller matrix or their combinations such as Stokes vector, degree of linear polarization (DOLP) and degree of circular polarization (DOCP). Our imaging polarimeter was similar in that it produced two combinations of 16 Mueller components.

Axisymmetrical Mueller matrix polarimeter

SPIE Proceedings, 2009
Mueller matrix polarimeter using the axisymmetrical polarized and analyzed optics is proposed. The axisymmetrical optics has a potential to bring out the polarization properties of a sample which kept in beam spot. A key device of this method is a detector named "a ring beam detector".

Mueller matrix microscopic ellipsometer

Optics Communications, 2013
Abstract We propose a Mueller matrix ellipsometer based on imaging of the exit pupil of a microscope objective lens. The instrument had a polarizer and a rotating phase retarder on the polarizing arm and a polarizer (analyzer) on the analyzing arm. A vector F representing the optical effect from the objective lens to the detector was obtained by ...

Visible Mueller matrix spectropolarimetry

SPIE Proceedings, 1997
A Mueller matrix spectropolarimeter operating between 400- 900nm has been developed for optical element characterization at The University of Alabama in Huntsville. Mueller matrices are measured as a function of wavelength and the spectral behavior of the polarization properties can be determined. Measurements of an achromatic retarder in transmission,
