| 中文摘要 | a theoretical study of the behaviour of partially coherent beams propagating through oceanic turbulence has been performed. based on the previously developed knowledge of beam spreading of a partially coherent beam in the atmosphere and the spatial power spectrum of the refractive index of ocean water, we study the normalized root-mean-square width of a partially coherent beam on propagation through oceanic turbulence and its turbulence distance which may be a measure of turbulence resistance. our analysis indicates that the behaviour of partially coherent beams on propagation may be described by the rate of dissipation of the mean-squared temperature chi(t) and that of salinity chi(s). in terms of a quantity w that defines the contributions of the temperature and salinity distributions to the distribution of the refractive index, chi(s) could be written as a function of chi(t) and w. therefore, the behaviour of partially coherent beams on propagation can be characterized only by chi(t) for a given w. the results are shown for curved surfaces, from which one can see that partially coherent beams exhibit robust turbulence resistance when the water volume has a smaller chi(t). |
