Mueller matrix spectroscopic ellipsometry of multiferroics
… analysis of the experimental data. Initially, Mueller matrix spectroscopic ellipsometry is reviewed. Analysis for optical spectra measured for isotropic Dy_3Fe_5O_{12} is given, for which contributions from magnetic and electric excitations are identified and the absence of strong …

Mueller-matrix-based analysis for second-harmonic generation imaging
… involving polarization investigation. The Mueller matrix formalism demonstrates a polarization-based analysis approach for assessment of varying samples. The associated second-order Mueller matrices are generated by applying image processing algorithms to sub-grids of image sets obtained …

Second-harmonic generation-based Mueller matrix polarization analysis of collagen-rich tissues
… correlations of the cell and its surrounding matrix. Second-harmonic generation (SHG) microscopy is especially well-suited as an image acquisition technique, due to its specificity to the non-centrosymmetric structure of collagen, and inherent confocality which enables three-dimensional …

Determination of Mueller matrix elements in the presence of imperfections in optical components
… was originally introduced to determine nine Mueller matrix elements from Fourier analysis of the output signal of a photodetector. The arrangement is modified to the P'PSAA' arrangement where P' and A' represent fixed polarizers that are added at both ends with the speed ratio of the rotating …

System Design, Noise Reduction, and Improved Dimension Reconstruction for High Performance Ellipsometry
… quantified by ellipsometric parameters or a Mueller matrix. The experimental results are then fitted to an optical model to extract the sample’s critical dimensions and/or optical properties. This thesis improves the performance of ellipsometry through three aspects. The first part of this …

Experimental study of non-resolved active polarimetry for space surveillance
… (incident angles from 0° to 90°) geometries. The Mueller matrix of each material is then estimated as a function of the illumination and viewing angles. The results reveal notable trends in the materials' geometry-dependent polarimetric properties, particularly diattenuation (D), retardance (R), …

Polarimetric Characterization Of Random Electromagnetic Beams And Applications
… direct application of the cross-spectral density matrix formalism, it is shown that the spectral and the polarimetric characteristics of light can be controlled by adjusting the correlations between parallel components of polarization propagating through the two arms of the interferometer. When …

Analysis of Mueller matrices of metamaterials and multiferroics
… models for data analysis. Berreman's 4 x 4 matrix formalism is used to derive forward models for the optical spectra of Reflectivity, Transmission, Rotating Analyzer Ellipsometry (RAE), and Mueller Matrices (MM). The forward models incorporate the relative electric permittivity tensor …
