WebDec 23, 2024 · Topological optical response Given an understanding of geometry, one interesting question is about its topology. Topological invariants can be defined using standard methods in Riemannian geometry. We would like to show you a description here but the site won’t allow us. WebFeb 26, 2007 · MTF is the spatial frequency response of an imaging system or a component; it is the contrast at a given spatial frequency relative to low frequencies. Spatial frequency is typically measured in cycles or line pairs per millimeter (lp/mm), which is analogous to cycles per second (Hertz) in audio systems. Lp/mm is most appropriate for film cameras, …

Nonlinear effects fall into two qualitatively different categories, parametric and non-parametric effects. A parametric non-linearity is an interaction in which the quantum state of the nonlinear material is not changed by the interaction with the optical field. As a consequence of this, the process is "instantaneous". Energy and momentum are conserved in the optical field, making phase match… WebApr 3, 2024 · Purpose: To characterize rat retinal responses after optic nerve transection (ONT) by visible-light optical coherence tomography (vis-OCT). Methods: Unilateral ONT was performed in Brown Norway rats (n = 8). In vivo, vis-OCT retinal imaging was performed on the experimental eyes before ONT (baseline), and two days, one week, two weeks, and …
WebIntroduction: The organic compounds which contain a “push–pull” system, that means a couple donor (D)–acceptor (A) connected to a system which contributes to the delocalization of the π-electrons, define the classic structures with optical response due to large hyperpolarizabilities. WebOct 3, 2012 · The optical modulation is produced by the deliberate change of the real part Δ n′ of the optical index, through the electro-optic effect, or of the imaginary part Δ n″ through laser gain or absorption control. The general expression for the refractive index n ( t) of the driven modulating device is in the form: (3.36)
