For underwater optical wireless communication (UOWC), the influence of waves close to the water's surface cannot be ignored. We build an experimental system of UOWC in a laboratory environment, where two fans are employed to produce water waves to simulate the turbulent water surface. The propagation and scattering of the input light are experimentally investigated, which shows that the scattering depends on the intensity of the water surface wave as well as the depth of its turbulence. Although at the receiver the laser spots are random and chaotic, their centroid drifts present spatial dependence, which is then investigated from the statistical point of view. Such characteristics may provide guidance to the optimization of receiving, tracking, and aiming devices.
对于水下光无线通信（UOWC）而言，靠近水面的波浪的影响不容忽视。我们在实验室环境中构建了一个UOWC实验系统，其中使用两个风扇产生水波以模拟湍流的水面。通过实验研究了输入光的传播和散射，结果表明散射取决于水面波的强度及其湍流深度。尽管在接收器处激光光斑是随机且混乱的，但其质心漂移呈现出空间依赖性，随后从统计学角度对其进行了研究。这些特性可为接收、跟踪和瞄准设备的优化提供指导。
