Polarization ray tracing and polarization aberration compensation in reflective, astronomical telescopes [PDF]
Optical Modeling and Performance Predictions X, 2018 Assessing and optimizing polarization performance in the context of ray-based optical design can be challenging. We describe an approach to this problem that decouples polarization effects from optical system geometry for reflective systems.

The Polarization Ray Tracing Calculus
Frontiers in Optics 2014, 2014 The polarization ray tracing calculus facilitates the analysis of polarization dependent point spread functions and optical transfer functions, and can integrate many different polarization models including thin films, anisotropic materials, anisotropic multilayers, diffractive optics, and liquid crystals.

Prospects for Ray-tracing Light Intensity and Polarization in Models of Accreting Compact Objects Using a GPU [PDF]
The Astrophysical Journal Supplement Series, 2023 The Event Horizon Telescope (EHT) has recently released high-resolution images of accretion flows onto two supermassive black holes. Our physical understanding of these images depends on the accuracy and precision of numerical models of plasma and ...

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.

Ray-tracing analysis for cross-polarization scattering diagnostic on MAST-upgrade spherical tokamak [PDF]
Review of Scientific Instruments, 2021 A combined Doppler backscattering/cross-polarization scattering (DBS/CPS) system is being deployed on MAST-U for simultaneous measurements of local density turbulence, turbulence flows, and magnetic turbulence. In this design, CPS shares the probing beam with the DBS and uses a separate parallel-viewing receiver system.

Analysis of polarization characteristics of freeform surface optical system [PDF]
ITM Web of Conferences, 2022 Freeform surfaces are widely used in off-axis optical systems with large aperture, large field of view, and long focal length. The polarization effect caused by the non-rotationally symmetrical shape has an impact on the system’s polarization imaging ...
