1 November 1990What is wrong in extended source adaptive optics?
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).
