| 中文摘要 | based on the extended huygens-fresnel principle, the mutual coherence function of quasi-monochromatic electromagnetic gaussian schell-model (egsm) beams propagating through turbulent atmosphere is derived analytically. by employing the lateral and the longitudinal coherence length of egsm beams to characterize the spatial and the temporal coherence of the beams, the behavior of changes in the spatial and the temporal coherence of those beams is studied. the results show that with a fixed set of beam parameters and under particular atmospheric turbulence model, the lateral coherence of an egsm beam reaches its maximum value as the beam propagates a certain distance in the turbulent atmosphere, then it begins degrading and keeps decreasing along with the further distance. however, the longitudinal coherence length of an egsm beam keeps unchanging in this propagation. lastly, a qualitative explanation is given to these results.
