To investigate the influence of oceanic turbulence on single photon capture probability, this paper derives the single photon capture probability model in the turbulent ocean environment. The entire research is based on Hermite Gaussian beam and Nikishov oceanic turbulence model and follows the rules of Rytov approximation and Kolmogorov spectrum. The influence of different oceanic turbulence parameters on single photon capture probability is also analyzed. The results show that the single photon capture probability decreases significantly after one hundred meters of transmission in the turbulent ocean environment. Besides, as the temperature variance dissipation rate increases, the single photon capture probability decreases. When the salinity factor dominates the oceanic turbulence, the single photon capture probability also decreases and the salinity change has a significant impact on the single photon capture probability of the turbulent ocean environment. Increasing the receiver aperture value and shortening the pulse interval can effectively improve the single photon capture probability. However, an increase in the temperature variance dissipation rate and a decrease in the transmission distance can reduce the influence of the pulse interval on the single photon capture probability.
