Coherence and visibility for vectorial light.

Two-path interference of transversal vectorial waves is embedded within a larger scheme: this is four-path interference between four scalar waves. This comprises previous approaches to coherence between vectorial waves and restores the equivalence between correlation-based coherence and visibility.

Exploiting coherence in hierarchical visibility algorithms

We present a series of simple improvements that make use of temporal and spatial coherence in the scope of hierarchical visibility algorithms. The hierarchy updating avoids visibility tests of certain interior nodes of the hierarchy. The visibility propagation algorithm reuses information about visibility of neighbouring spatial regions. Finally, the conservative hierarchy updating avoids visib...

Exploiting coherence in 2.5-D visibility computation

Visibility computation is used to reduce the amount of geometry that must be passed to the rendering engine. The model is subdivided into subvolumes called “cells”, and the visibility algorithm computes the set of cells that can at least partly be seen from the given viewpoint Airey [Aire90] called this the “potentially visible set” (PVS). The geometry associated with these cells (walls, interi...

Interference due to Coherence Swapping

We propose a method called “coherence swapping” which enables us to create superposition of a particle in two distinct paths, which is fed with initially incoherent, independent radiation. This phenomenon is also present for the charged particles, and can be used to swap the effect of flux line due to the Aharonov-Bohm effect. We propose an optical version of experimental setup to test the cohe...

Fidelity and coherence measures from interference.

By utilizing single particle interferometry, the fidelity or coherence of a pair of quantum states is identified with their capacity for interference. We consider processes acting on the internal degree of freedom (e.g., spin or polarization) of the interfering particle, preparing it in states rho_{A} or rho_{B} in the respective path of the interferometer. The maximal visibility depends on the...
