Birefringent Polarization Ray Tracing
Optical Design for Photonics, 1993The fundamental tool used for design and analysis of optical systems is geometric ray tracing. In isotropic, homogeneous, non-optically active media the procedure is simple -- rays travel in straight lines except at interfaces, where reflection and refraction occur.

Challenges in Polarization Ray Tracing
International Optical Design Conference and Optical Fabrication and Testing, 2010New polarization methods allow the ray tracing simulation of polarization critical components, including multilayer biaxial films, anisotropic and gyrotropic crystals, electro-optical, magneto-optical, and stressoptical modulators, photonic crystals and meta-materials.

Polarization Ray Tracing in Twisted Liquid Crystal Systems
Molecular Crystals and Liquid Crystals, 2002In this paper it will be presented different ray trace models that are able to simulate uniaxial birefringent optical elements with twisted structure. There exist already methods to calculate the optical behavior of birefringent elements (including angular dependence) such as the Jones matrix method [2].

Optical Engineering, 1989
A ray representing a vector wave is traced through an optical system. The electric field perpendicular to the (ray) direction of propagation is represented by a Jones vector. At each surface the results of a thin-film calculation are used to form a "surface" Jones matrix.

Topics in polarization ray tracing for image projectors
SPIE Proceedings, 2005Many subtle effects arise when tracing polarization along rays that converge or diverge to form an image. This paper concentrates on a few examples that are notable for the challenges they pose in properly analyzing vector imaging problems. A striking example is the Federov-Imbert shift, in which coating phase-shifts cause a reflected beam to ...

Progress in polarization ray tracing
SPIE Proceedings, 1994Polarization ray tracing is a collection of methods that extend geometrical ray tracing allowing the calculation of the evolution of polarization states along ray paths and the determination of the intrinsic polarization properties, such as diattenuation and retardance, associated with ray paths.

Polarization Ray Tracing for Space Optics
Optics and Photonics News, 2006Polarization ray tracing made its debut as a bona fide feature of optical design and analysis software about 20 years ago. This article traces how one of the first industrial strength automated PRT capabilities was created.

Applied Optics, 2016
The polarization properties of a two-axis periscopic optical scanner constituted by a pair of rotating planar mirrors have been studied by using the three-dimensional polarization ray-tracing matrix method. The separate and cumulative matrices that define the transformation of the polarization state are obtained and expressed in terms of the rotation ...

Characterization of DKIST retarder components with polarization ray tracing
SPIE Proceedings, 2014Super achromatic retarders and polychromatic modulators are required to meet the polarimetry specifications of the Daniel K. Inouye Solar Telescope. These components have been analyzed and toleranced using a birefringent polarization ray trace over wavelength and field of view.

Three-dimensional polarization ray tracing in electro-optic crystals
Optics Communications, 2020Abstract Electro-optic crystals are extensively utilized to manipulate polarized light. In this paper, a general and accurate three-dimensional polarization ray tracing calculus for characterizing the evolution of polarization state in electro-optic crystals is reported for the first time.
