Speckle dinámico — El Speckle dinámico en Física es un resultado de la evolución temporal de un diagrama de speckle en el que variaciones en los elementos dispersores responsables por la formación de la figura de interferencia en la situación estática son las… … Wikipedia Español
Dynamic speckle — Figure 1 A dynamic speckle from a maize seed that seems to “boil” faster in the areas where the scatterers are more active, in this case in the embryo and in a river like in the crack. In physics, dynamic speckle is a result of the temporal… … Wikipedia
Astronomical seeing — Schematic diagram illustrating how optical wavefronts from a distant star may be perturbed by a layer of turbulent mixing in the atmosphere. The vertical scale of the wavefronts plotted is highly exaggerated. Astronomical seeing refers to the… … Wikipedia
Optical heterodyne detection — is an important special case of heterodyne detection. In heterodyne detection, a signal of interest at some frequency is non linearly mixed with a reference local oscillator (LO) that is set at a close by frequency. The desired outcome is the… … Wikipedia
Diffusing-wave spectroscopy — (DWS) is an optical technique derived from dynamic light scattering (DLS) that studies the dynamics of scattered light in the limit of strong multiple scattering.[1][2] It has been widely used in the past to study colloidal suspensions, emulsions … Wikipedia
Coherence (physics) — In physics, coherence is a property of waves that enables stationary (i.e. temporally and spatially constant) interference. More generally, coherence describes all properties of the correlation between physical quantities of a wave. When… … Wikipedia

Optical interferometry — combines two or more light waves in an optical instrument in such a way that interference occurs between them. Early interferometers used white light sources and also monochromatic light from atomic sources (e.g., Young s double slit experiment… … Wikipedia
