In a recent publication [Opt. Lett.37, 2970 (2012)10.1364/OL.37.002970], a novel class of planar stochastic sources, generating far fields with flat intensity profiles, was introduced. In this paper we examine the behavior of the spectral density and the state of coherence of beamlike fields generated by such sources on propagation in free space and linear isotropic random media. In particular, we find that at sufficiently large distances from the source, the medium destroys the flat intensity profile, even if it remains such for intermediate distances from the source.
在最近的一篇出版物[《光学快报》37, 2970 (2012) 10.1364/OL.37.002970]中,引入了一类新型的平面随机源,其产生具有平坦强度分布的远场。在本文中,我们研究了此类源所产生的束状场在自由空间和线性各向同性随机介质中传播时的谱密度行为和相干态。特别地,我们发现,在离源足够远的距离处,即使在离源的中间距离处强度分布仍保持平坦,介质也会破坏这种平坦的强度分布。
