При этом прямолинейные подходы, игнорирующие структурные свойства атмосферной турбулентности и самой активной оптической системы, приводят к алгоритмам со сложностью, пропорциональной четвертой степени диаметра апертуры. Показано, что учет структурных свойств атмосферной турбулентности, а также самой активной оптической системы позволяют существенно снизить вычислительную сложность, приблизившись по порядку к квадрату диаметра апертуры. Предложен подход, основанный на эффективном построении команд для деформируемых зеркал многосопряженной адаптивной системы при уже известном объемном распределении турбулентности с учетом структурных свойств самой активной оптической системы. Эффективность предложенного подхода продемонстрирована на примере системы адаптивной оптики 30-метрового телескопа с шестислойной моделью атмосферной турбулентности.</p></abstract><trans-abstract xml:lang="en"><p>The necessity of correcting the perturbations related to light propagation in the turbulent atmosphere and obtaining the diffraction-limited images requires computer processing of a large information flow in real time. Here the straightforward approaches, which ignore the structural properties of the atmospheric turbulence and the active optical system itself, lead to algorithms with complexity proportional to the fourth power of the aperture diameter. In the paper it is shown that taking into account the structural properties of atmospheric turbulence as well as the active optical system itself allows to significantly reduce the complexity coming close to the second power of the diameter. The approach is proposed, which is based on the efficient construction of deformable mirror commands in a multi-conjugate adaptive system in the case of already known turbulence volume distribution taking into account structural properties of the active optical system itself. The efficiency of the proposed approach is demonstrated by the example of the system of adaptive optics of a 30-meter telescope pupil with a 6-layer atmospheric turbulence model.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>многосопряженная адаптивная оптика</kwd><kwd>томографическое фазовое восстановление</kwd><kwd>структурированные матрицы</kwd><kwd>обработка сигналов в реальном времени</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Multi-Conjugate Adaptive Optics</kwd><kwd>tomographic phase reconstruction</kwd><kwd>structured matrices</kwd><kwd>real-time signal processing</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Piatrou P.
