Star imaging under the influence of angular anisoplanatism in turbulent atmosphere

Three-dimensional numerical simulation of the propagation of radiation from a natural star through a turbulent atmosphere to a telescope located on the Earth as well as its imaging with the help of adaptive optics and a reference source technique, has been carried out. The verification of the calculation model has been performed. The accuracy of determining the angular coordinate of the star using radiation of another natural star located outside the isoplanar region at different outer scales of turbulence has been investigated and compared with approximate analytical data.
