Three-dimensional polarization ray tracing calculus for partially polarized light
Optics Express, 2017 Calculating the evolution of polarization for all polarization states of light in optical systems, in global coordinates, is an important, yet challenging task. This calculation exists for completely polarized light, but has not yet been developed for partially polarized light.

General Purpose Ray Tracing and Polarized Radiative Transfer in General Relativity [PDF]
The Astrophysical Journal, 2018 AbstractRay tracing is a central tool for constructing mock observations of compact object emission and for comparing physical emission models with observations. We presentArcmancer, a publicly available general ray-tracing and tensor algebra library, written in C++and providing a Python interface.Arcmancersupports Riemannian and semi-Riemannian spaces
