研究了部分相干光束在湍流介质中均方根空间和角度特性的扩展。光束的角展宽被证明是类似扩散的。光束的均方根宽度的动态被发现是由自由空间衍射和湍流扩散的相互作用。我们的研究结果表明，在这种情况下，部分相干光束是不太敏感的大气湍流所造成的失真比完全相干光束。(C)2002年由Elsevier Science B.V.出版
We study the spreading of the rms spatial and angular characteristics of partially coherent beams in turbulent media. The angular broadening of a beam is shown to be diffusion-like. The dynamics of the rms width of the beam is found to be determined by the interplay of free-space diffraction and turbulent diffusion. Our results indicate the conditions under which partially coherent beams are less sensitive to distortions caused by the atmospheric turbulence than are fully coherent beams.
