Beating atmospheric scintillation at millimeter and submillimeter wavelengths
The distorting effects of turbulence on images from a radio astronomy interferometer may be dramatically reduced by using a second instrument that monitors the atmosphere in real time.
The planned GRAVITY instrument will use optical interferometry to track the motion of matter in close proximity to the Galactic Center's black hole.
