... systems, which use two or more guide stars instead of one as references to sense the atmospheric turbulence in the instrument's field of view, and two or more deformable mirrors to correct for it. ...

... system were made possible by adaptive optics technology used to correct in real time for atmospheric turbulence, the shimmering or blinking of starlight as it passes through the earth's atmosphere. ...

... of 100-500 seconds, too low for humans to hear - was discovered in 1998 and ascribed to atmospheric turbulence. But in 2004, Romanowicz and UC Berkeley colleague Junkee Rhie showed that the source of ...
