Fast Reliable Ray-tracing of Procedurally Defined Implicit Surfaces Using Revised Affine Arithmetic [PDF]
, 2009 Fast and reliable rendering of implicit surfaces is an important area in the field of implicit modelling. Direct rendering, namely ray-tracing, is shown to be a suitable technique for obtaining good-quality visualisations of implicit surfaces. We present

Three-dimensional polarization ray-tracing Mueller algorithm for an optical system with arbitrary surface type [PDF]
, 2023 In order to investigate the relationship between the interface parameters of an optical interface/system and its polarization characteristics, a three-dimensional (3D) polarization ray-tracing Mueller algorithm is proposed in this paper.

Real-Time Ray Tracing With Polarization Parameters
, 2020 Bakgrund. Realtidsrenderarna som används i videospel och liknande grafikapplikationer simulerar inte ljusets polarisering. Polariseringsinformation har tidigare implementerats i vissa stålföljningsbaserade (ray-traced) offline-renderare för att simulera polariseringsfilter och diverse optiska effekter. Eftersom strålföljning har blivit allt vanligare i

HabEx polarization ray trace and aberration analysis [PDF]
Space Telescopes and Instrumentation 2018: Optical, Infrared, and Millimeter Wave, 2018 The flux difference between a terrestrial exoplanet and a much brighter nearby star creates an enormous optical design challenge for space-based imaging systems. Coronagraphs are designed to block the star’s flux and obtain a high-dynamic-range image of the exoplanet. The contrast of an optical system is calculated using the point spread function (PSF).

Interactive ray shading of FRep objects [PDF]
, 2008 In this paper we present a method for interactive rendering general procedurally defined functionally represented (FRep) objects using the acceleration with graphics hardware, namely Graphics Processing Units (GPU).

Single acquisition reconstruction of nonlinear susceptibility and Raman tensors at the diffraction limit [PDF]
APL PhotonicsQuantitative extraction of nonlinear optical tensors at the microscale typically requires sequential polarization scans, mechanical rotations, and careful correction of high-NA polarization distortions.

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.

A simple P-wave polarization analysis: its application to earthquake location
Annals of Geophysics, 1994 We present a method for hypocentral location which takes into account all three components of ground motion and not only the vertical one, as it is usually done by standard least-square techniques applied to arrival times.
