• Astronomical optical interferometry — One of the first astronomical interferometers was built on the Mount Wilson Observatory s reflector telescope in 1920 in order to measure the diameters of stars. The red giant star Betelgeuse was among the first to have its diameter determined in …   Wikipedia

• Interferometry — is the technique of using the pattern of interference created by the superposition of two or more waves to diagnose the properties of the aforementioned waves. The instrument used to interfere the waves together is called an interferometer.… …   Wikipedia

• Interference (wave propagation) — Two point interference in a ripple tank. In physics, interference is the phenomenon in which two waves superpose each other to form a resultant wave of greater or lower amplitude. Interference usually refers to the interaction of waves that are… …   Wikipedia

• Fabry–Pérot interferometer — Étalon redirects here. For the commune in Somme, France, see Étalon, Somme. Interference fringes, showing fine structure, from a Fabry–Pérot etalon. The source is a cooled deuterium lamp. In optics, a Fabry–Pérot interferometer or etalon is typic …   Wikipedia

• Interferometric visibility — The interferometric visibility (also known as interference visibility or fringe visibility or just visibility ) quantifies the contrast of interference in any system which has wave like properties, such as optics, quantum mechanics, water waves,… …   Wikipedia

• Fabry-Pérot interferometer — In optics, a Fabry Pérot interferometer or etalon is typically made of a transparent plate with two reflecting surfaces, or two parallel highly reflecting mirrors. (Technically the former is an etalon and the latter is an interferometer, but the… …   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
