摘　　要：基于部分相干光的传输定律 ,对多色部分空间相干光的长程大气传输做了研究 .结果表明 ,无论是否满足定标律 ,大气湍流会引起多色部分空间相干光的光谱移动和光束扩展 ;多色部分空间相干光光束扩展比多色完全空间相干光受湍流的影响小 .然而 。Based on the propagation law of partially coherent light, the long-distance propagation of the spatially partially coherent polychromatic light through the atmosphere is studied. It is shown that the atmospheric turbulence gives rise to spectral shift and to beam spreading of spatially partially coherent polychromatic light whether the scaling law is satisfied or not. The influence of turbulence on beam spreading of the spatially partially coherent polychromatic light is smaller than that of spatially fully coherent polychromatic light. However, the influence of bandwidth on the intensity distribution is relatively small.
