Scintillation
Encyclopedia
Scintillation can refer to:
- Scintillation (astronomy)Scintillation (astronomy)Scintillation or twinkling are generic terms for rapid variations in apparent brightness or color of a distant luminous object viewed through a medium, most commonly the atmosphere ....
, atmospheric effects which influence astronomical observations - Interplanetary scintillationInterplanetary scintillationIn astronomy, interplanetary scintillation refers to random fluctuations in the intensity of radio waves of celestial origin, on the timescale of a few seconds. It is analogous to the twinkling one sees looking at stars in the sky at night, but in the radio part of the electromagnetic spectrum...
, fluctuations of radio waves caused by the solar wind - Scintillation (physics)Scintillation (physics)Scintillation is a flash of light produced in a transparent material by an ionization event. See scintillator and scintillation counter for practical applications.-Overview:...
, a flash of light produced in certain materials when they absorb ionizing radiation - Scintillation (radar)Scintillation (radar)Scintillation is a fluctuation in the amplitude of a target on a radar display. It is closely related to target glint, or wander, an apparent displacement of the target from its mean position. This effect can be caused by a shift of the effective reflection point on the target, but has other causes...
, an apparent rapid target displacement occurring on radar displays - Scintillation (medicine), a rapidly oscillating pattern of visual distortions, often associated with migraine aura
- Scintillation counterScintillation counterA scintillation counter measures ionizing radiation. The sensor, called a scintillator, consists of a transparent crystal, usually phosphor, plastic , or organic liquid that fluoresces when struck by ionizing radiation. A sensitive photomultiplier tube measures the light from the crystal...
, a device that measures ionizing radiation - Scintillating grid illusionGrid illusionA grid illusion is any kind of grid that deceives a person's vision. The two most common types of grid illusions are Hermann grid illusion and the Scintillating grid illusion.-Hermann grid illusion:...
, an image in which compounded color contrasts cause an optical illusion of visual artifacts
