Estimation of anisoplanatism in the turbulent structured atmosphere


A method is proposed for the simplified numerical estimation of the anisoplanatism of an adaptive optical system operating in the observational mode through the turbulent atmosphere. The method takes into account the finite value of the outer scale of turbulence and allows for the anisoplanatism to be estimated for the inhomogeneous atmosphere with different distributions of the parameters over the path. The different distributions of C 2 n corresponding to vertical and horizontal atmospheric paths have been simulated. It is shown that the distribution of inhomogeneities on the path significantly affects the anisoplanatism.
