Three-dimensional coherence of light speckles: Theory
We provide a detailed analysis of the three-dimensional spatial coherence properties of light speckles, based on very general assumptions. We show that, while in the deep Fresnel region close to the source the longitudinal coherence of speckles is ruled by the laws of ordinary diffraction, on approach to the Fraunhofer zone the longitudinal coherence length tends to become infinite. We offer bo...
متن کاملThree-dimensional coherence of light speckles: Experiment
We provide an experimental detailed study of the three-dimensional coherence properties of light speckles produced by different tunable pseudothermal sources. Our findings confirm the theoretical prediction of the companion article A. Gatti et al., Phys. Rev. A 78, 063806 2008 , according to which the longitudinal coherence of the speckles is ruled by ordinary diffraction laws only in the deep-...
متن کاملTheory of three-dimensional nanocrescent light harvesters.
The optical properties of three-dimensional crescent-shaped gold nanoparticles are studied using a transformation optics methodology. The polarization insensitive, highly efficient, and tunable light harvesting ability of singular nanocrescents is demonstrated. We extend our approach to more realistic blunt nanostructures, showing the robustness of their plasmonic performance against geometric ...
متن کاملReview of Coherence in Three - Dimensional Category Theory
Nick Gurski’s new book addresses some central concerns of the subject known as higher category theory; and yet, it is some distance from what many people now understand by that term. This may puzzle some. I will therefore begin by locating Gurski’s book within the mathematical landscape. Let n ∈ N ∪ {∞}. Roughly, an n-category consists of some objects, some 1-morphisms between objects, some 2-m...
متن کاملLight diffraction by a three-dimensional object: differential theory.
The differential theory of diffraction of light by an arbitrary object described in spherical coordinates is developed. Expanding the fields on the basis of vector spherical harmonics, we reduce the Maxwell equations to an infinite first-order differential set. In view of the truncation required for numerical integration, correct factorization rules are derived to express the components of D in...
