Paper Abstract

Atmospheric turbulence is a major limitation to optical high resolution imaging systems observing through the lower atmosphere. In most conditions, it limits the angular resolution to about one arcsecond, which is the resolution of a small 10 cm telescope operating in the visible. From a theoretical standpoint, its effects on beam propagation can be rather well predicted with the knowledge of atmospheric conditions and the assumption of the Kolmogorov turbulence law. Then, the practical problem turns out to be the characterization of propagation conditions and the compensation of turbulence effects.
