Scintillation calculations for partially coherent general beams via extended Huygens-Fresnel integral and self-designed Matlab function

摘要: We 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 average intensity squared intensity. This way, integrations are performed semi-analytic manner by associated function, this avoids lengthy, time-consuming error prone hand derivations. The results obtained fundamental higher-order sinusoidal annular Gaussian beams. By plotting index against propagation distance source size, we illustrate on-axis behaviors these Accordingly, it is found that within specific parameter ranges, fundamental, capable offering less scintillations, comparison beam.
