Abstract

In optical radar, communication, and energy transfer one frequently encounters the problem of transportating optical radiation energy to an object located in a randomly inhomogeneous medium. The scattering by the refractive index inhomogeneities of such a medium reduces the average intensity in the axial part of light beam and generates fluctuations of the intensity, so that the result is a considerable deterioration of the energy characteristics of systems operating in such media. The amplitude and phase fluctuations of Gaussian beam, propagated through the turbulent atmosphere, are not spatially homogeneous in a transversal beam section. Here we introduce an estimation criterion for beam computed for some different values of aperture/beam diameter ratio. The numerical simulations of beam propagation through the random-inhomogeneous media were performed using modified splitting method. The results of numerical experiments as well as the behavior of proposed criterion are discussed.
