Algorithm for formation of an infinite random turbulent screen

摘要

A new approach to formation of random turbulent screens is proposed. Simulation of temporal fluctuations of refractive index inhomogeneities helps in removing the spatial periodicity arising at the transversal displacement of the screen. This improvement allows the formation of random turbulent screens having an infinite extension. Some examples of the problems of atmospheric turbulent optics are presented along with their numerical solution obtained using the algorithm proposed. The problems under consideration involve simulating long (in time) observation series of characteristics of laser beams propagating through the atmosphere.
