Decomposition of angle resolved spectroscopic Mueller matrices from Scarabaeidae beetles
, 2015 We use angle-dependent Mueller-matrix spectroscopic ellipsometry (MMSE) to determine Mueller matrices of Scarabaeidae beetles which show fascinating reflection properties due to structural phenomena in the exocuticle which are often depolarizing.

Decomposition of mueller matrices in pure optical media
, 2003 The mathematical model of Mueller matrices is able to represent polarimetric properties of every material samples. In this paper an algebraic operation is performed to decompose a Mueller matrix M into the corresponding matrices of the pure optical media

Bayesian data reduction approaches in polarization imaging
EPJ Web of Conferences, 2010 The Stokes-Mueller formalism provides a coherent framework that permits obtaining polarization parameters from raw radiance acquisitions through a linear observation model. In polarization imaging, this observation model is extended to the whole image

On the noise and physical realizability of experimental polarimetric images
EPJ Web of Conferences, 2010 Optical polarimetric images are usually calculated from a set of intensity images recorded with different states of polarization of light [1] . Be cause these latter states are setup dependent, propagation of experimental noise to polarimetric images ...

Sum decomposition of Mueller matrices from beetle cuticles [Elektronisk resurs]
, 2015 Spectral Mueller matrices are very rich in information about physical properties of a sample. We have recently shown that polarizing properties like ellipticity and degree of polarization can be extracted from a Mueller matrix measured on a beetle ...
