| Statistical characteristics of light wave propagating in turbulent water are studied by using the approximation of the geometric optic. It is assumed that optical refractive-index fluctuations caused by the fluctuations of temperature and salinity. Model of the spectrum of optical refractive-index fluctuations was developed on the base of the Corrsin-Pao model of the spectrum of temperature fluctuations. It is shown that the structure function of phase and sum of the longitudinal and cross correlation functions of the angle of arrival of light wave are changed significantly depending on the contributions of temperature and salinity fluctuations in the refractive-index fluctuations. It is demonstrated that local bumps arise in the characteristics, shapes of curves are changed. The local extremums of the spectrum of refractive-index fluctuations are responsible for these anomalies. |
