Abstract

As a common dynamic phenomenon in seawater, turbulence can affect the performance of underwater light transmission. Monte Carlo turbulence model is used in this paper, and this model is based on the Monte Carlo method to simulate the transmission of photons in turbulence with changing refractive index. The results show that the received light intensity probability density distribution is lognormal under weak, moderate and strong turbulence. With the increase of the variations of temperature and salinity, the intensity of turbulence is enhanced, and the effect on the received light intensity is increased, which is manifested by the gradual increase of the scintillation index as well as the asymmetry of the probability density distribution of the received light intensity. In addition, it is found that the asymmetry of the probability density distribution of the received light intensity is affected by the field angle of the receiving end and the divergence angle of the transmitting end.
