Abstract

Based on the generalized Huygens-Fresnel principle, the expressions for the spectral degree of coherence of Gaussian-Schell model (GSM) beam through turbulent atmosphere is derived by using the incoherent superposition of higher-order Hermite-Gaussian beams. The influence of atmospheric turbulence on spatial correlation property is studied. It is shown that the spatial correlation property of beams becomes weaker with the increase of refraction index structure constant C_n² and the transmission instance.
