Abstract:

This paper examines current issues related to deriving analytical expressions for calculating fluctuations in optical wave parameters as they propagate through turbulent media with a non-Kolmogorov turbulence spectrum. The primary goal of this paper is to derive formulas for the dependence of optical wave parameter fluctuations on medium parameters. The primary analysis method utilizes theoretical calculations, supplemented by numerical computations using atmospheric models. Assuming that the integral turbulent energy is independent of the turbulence spectrum type, relationships between the structural parameters of the refractive index of the medium for different turbulence types are obtained. The results of this study allow the parameters of optical waves propagating in a random medium with a certain turbulence spectrum to be recalculated for media with different spectra. The results of this work can be used in the development of adaptive optics systems and in the study of turbulence along atmospheric optical paths.
