摘　　要：结合理论推导和角谱仿真,深入探讨标量光束和矢量光束在大气湍流中的聚焦传输特性,对比典型的标量光束(高斯光束)和矢量光束(柠檬矢量光束和径向偏振矢量光束)在弱、强湍流条件下的聚焦性能。研究发现,无论是在弱湍流还是在强湍流条件下,聚焦高斯光束在焦平面处的平均峰值功率密度最高,63.2%环围能量半径最小,但其闪烁指数则显著高于聚焦柠檬矢量光束。In this study,we conduct a thorough investigation into the focusing transmission characteristics of scalar and vector beams in atmospheric turbulence by combining theoretical derivations with angular spectrum simulations.We compare the focusing performance of typical scalar beams(Gaussian beam)and vector beams(lemon vector beam and radially polarized vector beam)under weak and strong turbulent conditions.Our research reveals that,whether it is in weak or strong turbulent conditions,the focused Gaussian beam exhibits the highest average peak power density and the smallest radius of 63.2%encircled energy at the focal plane.However,its scintillation index significantly exceeds that of the focused lemon vector beam.
