The Use of the Inhomogeneities of the Sodium Layer for Measuring the Atmospheric Turbulence, Including Tip-Tilt!

Abstract

An original method for measuring the atmospheric turbulence is described, capable of even measuring the tip-tilt, which normally requires a dedicated natural star and nowadays defines the practical limit of the adaptive optics technique. The method is based in the illumination of a wide area of the Sodium Layer, and to use their inhomogeneities as a reference. Sevaral analysis and simulation results will be presented.
