Abstract

The effectiveness of reconstruction of images formed by single- and multi-aperture systems and disturbed by atmospheric turbulence is analyzed. Based on the numerical simulation, we show that the use of multi-aperture observation systems for the computer correction of atmospheric disturbances under anisoplanatism allows a significant reduction of the exposure time. Main distortions are well corrected in this case during imaging for the short exposure time, which corresponds to the “frozen” turbulence of the medium. The time required for the correction of residual small-scale disturbances is an-order-of-magnitude shorter than in the case where long-exposure images are synthesized with traditional single-aperture observation systems.
