Abstract
Atmospheric turbulence phase screens are important for performance test of adaptive optics systems and image restoration algorithms. In recent years, more and more model based adaptive optics control algorithms, wave-front reconstruction algorithms and image restoration algorithms have been proposed. These algorithms have very strong prior information about properties of turbulence. Ordinary atmospheric turbulence phase screen generation methods would become inappropriate to test these methods, because these phase screen generation methods are also developed according to prior information of turbulence. In this paper, we will report our recent progress in building a digital twin of atmospheric turbulence phase screen, which automatically obtain models of atmospheric turbulence and generates phase screens directly. Our method has no prior assumptions about the statistical properties of turbulence phase screens, which make it adequate to test the performance of model based algorithms.
