TL;DR: In this article, an analysis of optical propagation through turbulence which causes fluctuations in the index of refraction is presented. But the authors assume that the index fluctuations are assumed to have spatial power spectra that obey arbitrary power laws and do not obey Kolmogorov's power spectral density model.

TL;DR: A method for widening the compensated field of view of an adaptive-optical telescope with multiple deformable mirrors and an array of artificial guide stars is investigated, and an ensemble of wavefront sensor measurements are used to estimate the contribution of a region of the atmosphere to the cumulative phase distortion.

TL;DR: In this article, the effects of anisoplanatism on the design of a 2m-diameter adaptive telescope using laser guide stars created in the mesospheric Na layer is considered.
