Ray Tracing Method
Although the optical microscope has been the main tool for observations of etched tracks in solid state nuclear track detectors for many years, there has been relatively little investigation about the optical characteristics of these tracks. This chapter describes the application of the ray tracing method to light propagation through these etched tracks. The method is shown to be able to reprod...
متن کاملRay effect in ray tracing method for radiative heat transfer
The ray effect in ray tracing method was analyzed and three new ray emitting methods for a surface element (method A, B and C) were presented. Numerical computations of viewfactors for three different typical configurations indicated that the proposed methods can significantly eliminate the ray effect. Compared with the conventional ray emitting method, the proposed methods, especially method C...
متن کاملLaser ray-tracing method for optical testing.
We have developed a novel laser ray-tracing method to measure aberrations in optical systems. It consists of delivering narrow laser pencils (by a laser scanner), recording the spots that are formed on the image plane (with a CCD camera), and computing the position of each centroid. This approach could be considered an experimental (approximate) implementation of standard numerical ray tracing....
متن کاملGlimm-Godunov's method for cosmic-ray-hydrodynamics
A numerical method for integrating the equations describing a dynamically coupled system made of a fluid and cosmic-rays is developed. In smooth flows the effect of CR pressure is accounted for by modification of the characteristic equations and the energy exchange between cosmic-rays and the fluid, due to diffusive processes in configuration and momentum space, is modeled with a flux conservin...
متن کاملA Three-Point Cosmic Ray Anisotropy Method
The two-point angular correlation function is a traditional method used to search for deviations from expectations of isotropy. In this paper we develop and explore a statistically descriptive three-point method with the intended application being the search for deviations from isotropy in the highest energy cosmic rays. We compare the sensitivity of a two-point method and a “shape-strength” me...
