By Vladimir P. Lukin, Boris V. Fortes

As a result of the large software of adaptive optical platforms, an figuring out of optical wave propagation in randomly inhomogeneous media has turn into crucial, and several other numerical versions of person AOS parts and of effective correction algorithms were built. This monograph comprises unique descriptions of the mathematical experiments that have been designed and conducted in the course of greater than a decade's worthy of research.

22) owing to the properties of the delta function. With allowance for the fact that the processes are normal, we can consider them as statistically independent and simulate them separately, thus obtaining (after integration) a process with the required spectral density. To implement this technique, we have developed a procedure for calculating the time spectra of the coefficient fluctuations of a Zernike expansion [Eq. 18)]. 1 shows the spectra calculated for the polynomials of the first, second, and third radial orders.
