On the equivalence of optimization metrics in Stokes polarimetry

Optical Engineering: The Journal of SPIE, 2019
. Optimization of polarimeters has historically been achieved using an assortment of performance metrics. Selection of an optimization parameter is, however, frequently made on an ad hoc basis.

An Approach to Extended Fresnel Scattering for Modeling of Depolarizing Soil-Trunk Double-Bounce Scattering

Remote Sensing, 2016
Focusing on scattering from natural media, dihedral (double bounce) scattering is often characterized as a soil-trunk double Fresnel reflection, like for instance, in most model-based decompositions.

Polarization Vector Rotations: Real, Spurious, Hidden and Imaginary

Galaxies, 2016
Large and variable polarization is an inherent property of a majority of blazars. Systematic rotations of the polarization vector have been claimed for several blazars. In some cases, however, the reality of these rotations may be questionable.
