The scintillation index of light emitting diode (LED) sources is evaluated when such sources are employed in oceanic wireless optical communication (UWOC) links. In the formulation, LED source radiation is taken to be perfectly incoherent with a Gaussian field distribution. We have utilized the scintillation index solution of an incoherent source in atmospheric turbulence, together with our recently obtained expression that expresses the structure constant of atmospheric turbulence in terms of the oceanic turbulence and UWOC link parameters. Oceanic turbulence parameters of interest are the ratio of temperature to salinity contributions to the refractive index spectrum, rate of dissipation of kinetic energy per unit mass of fluid, rate of dissipation of mean-squared temperature, and viscosity. UWOC link parameters are the LED source size, link length, and the wavelength. Scintillation index results are presented for various variations of the oceanic turbulence and UWOC link parameters.
当发光二极管（LED）光源应用于海洋无线光通信（UWOC）链路时，对其闪烁指数进行了评估。在公式中，LED光源辐射被视为具有高斯场分布的完全非相干光。我们利用了大气湍流中非相干光源的闪烁指数解，以及我们最近得到的一个表达式，该表达式根据海洋湍流和UWOC链路参数来表示大气湍流的结构常数。感兴趣的海洋湍流参数包括温度与盐度对折射率谱的贡献之比、单位质量流体的动能耗散率、均方温度耗散率和粘度。UWOC链路参数包括LED光源尺寸、链路长度和波长。给出了各种海洋湍流和UWOC链路参数变化下的闪烁指数结果。
