Abstract

In this paper we compare the impact on the turbulent wavefront Zernike modes, of a Kolmogorov and a Von Karman spectrum atmosphere with finite outer scale. We have simulated these effects analytically and numerically, for Natural and Laser Guide Star AO system, on axis and off- axis. The goal is to compare the effects of anisoplanatism, and re-evaluate the discussions on the pro's and con's of LGS vs. NGS on a perspective which includes also the presence of the outer scale.
