论文摘要
根据Rytov近似理论，我们得出了具有携带轨道角动量（OAM）模式的Powerexponent-phase相相的自动焦距（AAB）检测概率的分析表达。我们分析了海洋湍流对AAB-PEPV传播特性的影响。结果表明，当各向异性海洋湍流具有较大的单位质量流体动态耗散率，较大的内部比率因子和较高的各向异性因子时，AAB-PEPV梁在接收方的检测概率较高。同时，检测概率随温度变化耗散速率，温度和盐度贡献对折射率频谱的贡献而降低。此外，较大的功率指数相和AAB-PEPV梁具有较长的波长，AAB-PEPV梁具有更好的抗干扰。
According to Rytov approximation theory, we derive the analytical expression of the detection probability of the autofocusing Airy beam (AAB) with powerexponent-phase carrying orbital angular momentum (OAM) mode, AAB-PEPV. We analyze the influence of oceanic turbulence on the propagation characteristics of the AAB-PEPV. The results show that the AAB-PEPV beam has a higher detection probability at the receiver when the anisotropic ocean turbulence has a larger unit mass fluid dynamic energy dissipation rate, a larger internal ratio factor, and a higher anisotropy factor. At the same time, the detection probability decreases with the temperature change dissipation rate, the temperature and salinity contribution to the refractive index spectrum. In addition, the larger power exponential phase and the longer wavelength the AAB-PEPV beam has, the better anti-interference the AAB-PEPV beam has.
