As a result huge software of adaptive optical structures, an figuring out of optical wave propagation in randomly inhomogeneous media has develop into crucial, and several other numerical types of person AOS elements and of effective correction algorithms were constructed. This monograph includes particular descriptions of the mathematical experiments that have been designed and conducted in the course of greater than a decade's worthy of research.

In this case, the reference wave and the wave to be corrected propagate in the same direction. In a particular case in which a part of the energy of the wave to be corrected is directed onto the sensor of wavefront distortions, this wave also serves as a reference wave at the same time. In an image correction system such as a ground-based astronomical adaptive telescope, the source of the reference wave is either a natural or an artificial star. (We will return to this problem in Chapter 5). For a natural star, the main sources of the residual error of correction are angular anisoplanatism [14-18] and quantum noise connected with low radiation intensity.
