Abstract
The efficiency of retrieval of images distorted by atmospheric turbulence formed by single- and multiaperture systems is analyzed. It is shown in numerical simulation that the use of multiaperture observation systems for computer correction of atmospheric distortions under anisoplanatism can significantly reduce the exposure time. The main distortions are well corrected when imaging for a short exposure time, which corresponds to the case of a “frozen” turbulent medium. Correction of residual small-scale distortions requires an-order-of-magnitude shorter time than in the case of long-exposure imaging with the use of common single-aperture observation systems.
