摘要: In this paper, we analyze the propagation of Flat-topped beams (FTB) introduced by Li in turbulent atmosphere within regime weak fluctuations. We use paraxial approximation and Rytov theory to determine some parameters, factors characterizing fluctuations amplitude phase during its atmosphere. Thus, statistical moments as scintillation index, probability fade, excepted number fades per unit time, mean duration fade are found. The obtained theoretical results illustrated numerical calculations discussions.
