May 18, 2016 · In optics, a caustic is the envelope of light rays reflected or refracted by a curved surface or object, or the projection of that envelope of rays on another surface. You can think …

Radiation caustic (dashed circle) inside a dielectric sphere, ρ 0 = ρ cos α, ρ 0 and ρ are the radii of the caustic and the sphere, respectively, α is the incident angle of the ray in the sphere....

Nov 10, 2023 · A caustic is understood mathematically as the envelope function of multiple rays that converge in the Fourier domain (angular deflection measured at far distances). These are …

The caustic is a curve or surface to which each of the light rays is tangent, defining a boundary of an envelope of rays as a curve of concentrated light. [2] In some cases caustics can be seen …

Caustic • If a sheet is not degenerate, then the normal to the given surface passing through the principal center of curvature lying in the caustic sheet is tangent to the sheet at that point, and …

Radiation from light sources with calibrated energies in red and green spectral regions was also directed to the minispectrometer entrance.

ct: Gamma-ray pulsar profiles are widely believed to be dominated by caustic effects. The caustic pile-up of photons at a preferred pulse phase can be understood in two equivalent ways: either …

Jan 10, 2011 · Based on our theoretical calculations we find that these beams are caustic beams and the angles are the characteristic spin-wave caustic angles modified by the motion of the …

Caustic surfaces and irradiance for reflection and refraction from an ellipsoid, elliptic paraboloid, and elliptic cone. General formulas are derived for the caustic surface and irradiance over an …

In this paper we propose a technique for computing the ray caustic distance parameter on an arbitrary convex surface described by Non-Uniform Rational B-splines (NURBS) surface …
