Abstract The phenomena of birefringency may be ob-served when light arrives at an anisotropic crystal sur-face and refracts through it, causing the incident light ray to split into two rays; these become polarized in mu-tually orthogonal directions, and two images are formed. The principal goal

The rapid increase in the performance of graphics hardware, coupled with recent improvements in its programmability, have made graphics hardware acompelling platform for computationally demanding tasks in awide variety of application domains. In this report, we describe, summarize, and analyze the latest research in mapping general-purpose computation to graphics hardware. We begin with the technical motivations that underlie general-purpose computation on graphics processors (GPGPU) and describe the hardware and software developments that have led to the recent interest in this field. We then aim the main body of this report at two separate audiences. First, we describe the techniques used in mapping general-purpose computation to graphics hardware. We believe these techniques will be generally useful for researchers who plan to develop the next generation of GPGPU algorithms and techniques. Second, we survey and categorize the latest developments in general-purpose application development on graphics hardware.

graphics application, especially if a polarisation-aware rendering system is being used. This paper contains the complete derivation of the Fresnel coefficients for birefringent transparent materials, as well as for the direction cosines of the extraordinary ray and the Mueller matrices necessary

-plane birefringence requires knowledge of at least an approximate value for the material’s average refractive index.

ABSTRACT: In this study, we discuss the applications of a birefringence technique for online or off-line quantitative measurement of biaxial orientation in transparent films, sheets, bottles, etc. Absolute values of biaxial birefringence are measured in two directions using a technique based

Using a new formalism involving projection from the sphere of directions to the stereographic plane, and associated complex variables, explicit formulae are obtained for the two refractive indices and polarizations in optically anisotropic crystals that are both dichroic (absorbing) and chiral

The main refractive indices and the birefringence of MBBA and PPMAEBOBA10-2 g/cm3 in TCM nematic liquid crystals at room temperature were determined by interferometric means for some visible monochromatic radiations in the absence and in the presence of external electrostatic or alternate electric
