Abstract

Phase correction of a plane wave, propagating through a turbulent layer, is considered. The required adaptive corrector element size and the system bandwidth were found by numerical simulation. These requirements were determined to be the same as for weak intensity scintillation approximation. The size of the required segmented mirror element was found to be equal to Fried length r₀ while the tolerable time lag was r₀/V, where V is the wind velocity. However, the local slope sensors become therewith impractical as well as the tip-tilt correction over the corrector subapertures.
