Optical intensity interferometry through atmospheric turbulence [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 Conventional ground-based astronomical observations suffer from image distortion due to atmospheric turbulence. This can be minimized by choosing suitable geographic locations or adaptive optical techniques, and avoided altogether by using orbital platforms outside the atmosphere.
