extreme adaptive optics
  نوریک ِ نیاوشی ِ استوم  
nurik-e niyâveši-ye ostom
Fr.: optique adaptative extrême  

An → adaptive optics system with high-contrast imaging and spectroscopic capabilities. Extreme adaptive optics systems enable the detection of faint objects (e.g., → exoplanets) close to bright sources that would otherwise overwhelm them. This is accomplished both by increasing the peak intensity of point-source images and by removing light scattered by the atmosphere and the telescope optics into the → seeing disk.

See also: → extreme; → adaptive; → optics.
