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.

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.

Error analysis for Mueller matrix measurement

Journal of the Optical Society of America A, 2003
The linear errors of Mueller matrix measurements are formulated for misalignment, depolarization, and incorrect retardation of the polarimetric components. The measured errors of a Mueller matrix depend not only on the imperfections of the measuring system but also on the Mueller matrix itself.

A Mueller matrix model of Haidinger's brushes

Ophthalmic and Physiological Optics, 2003
Abstract Stokes vectors and Mueller matrices are used to model the polarisation properties (birefringence, dichroism and depolarisation) of any optical system, in particular the human eye. An explanation of the form and behaviour of the entoptic phenomenon of Haidinger's brushes is derived that complements and expands upon a previous ...

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".

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,

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.

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.
