Scintillation calculations for partially coherent general beams via extended Huygens-Fresnel integral and self-designed Matlab function. Applied Physisc B-Lasers And Optics, 100(3), 597-609. http://dx.doi.org/ 10.1007/s00340-010-4125-40946-2171http://hdl.handle.net/20.500.12416/1082We present scintillation calculations in weak atmospheric turbulence for partially coherent general beams based on the extended Huygens-Fresnel integral and a Matlab function designed to handle expressions both of the average intensity and the average squared intensity. This way, the integrations are performed in a semi-analytic manner by the associated Matlab function, and this avoids lengthy, time-consuming and error prone hand derivations. The results are obtained for the partially coherent fundamental and higher-order sinusoidal and annular Gaussian beams. By plotting the scintillation index against the propagation distance and source size, we illustrate the on-axis scintillation behaviors of these beams. Accordingly, it is found that within specific source and parameter ranges, partially coherent fundamental, higher-order sinusoidal and annular Gaussian beams are capable of offering less scintillations, in comparison to the fundamental Gaussian beameninfo:eu-repo/semantics/closedAccessSpace Optical CommunicationsWeak Atmospheric-TurbulenceBessel-Gaussian BeamsDark Hollow BeamsIntensity FluctuationsAnnular BeamsRytov MethodIndexPropagationCovarianceArticle100359760910.1007/s00340-010-4125-4
