Paper Abstract

Atmospheric turbulence severely degrades the quality and resolution of images captured by ground based telescopes. Although multiconjugate adaptive optics systems have the potential to compensate over a wide field of view they require characterization of the 3D structure of the atmosphere. Many of the existing remote sensing techniques that analyze scintillation measurements are restricted to binary star measurements, due to the ill-conditioning of the corresponding single star problem. In this paper we discuss the possibility of measuring the turbulent layers in the atmosphere using scintillation measurements made from a single star.
