Study of Aperture-Averaged Scintillation for a Partially Coherent Gaussian Schell-model Beam Propagation in Slant Atmospheric Turbulence
Based on the extended Huygens-Fresnel principle,scintillation of a partially coherent Gaussian Schell-model (GSM) beam propagation in weakly slant atmospheric turbulence is studied.The expression of aperture-averaging factor of the system receiver is derived.We analyzed the aperture-averaged scintillation index numerically.A comparison of the aperture-averaged scintillation of the beam propagation in slant path with that of the beam propagation in horizontal path is made.Results obtained show using partially coherent beams and considering aperture-averaging effect can decrease the scintillation and improve the optical communication system performance.
