Abstract
A novel method for the simulation of atmospheric turbulence degraded wavefronts is shown. The computer generated wavefronts contain all the statistical and spatial properties predicted for Kolmogorov type turbulence. The technique enables the generation of wavefronts from two separated point sources while maintaining the correct correlation. rfhe techniques was used to check the effects of anisoplanitism on the performance of wavefront compensation by adaptive optics using the modal correction. The dependance on the order of correction was estimated as well. It is shown that for strong turbulence, for extended sources, there is no benefit of correction beyond the third order (tilt).
