Abstract: (4399 Views)
In this paper the analytical expression for the elements of the cross-spectral density matrix of a partially coherent circular flat-topped beam propagating in northern part of the Persian Gulf turbulence has been derived. In calculations we have used the extended Huygens-Fresnel integral and variation of the rate of dissipation of turbulent kinetic energy of Persian Gulf. The turbulence effects on beam spreading and the aperture and lens effects on spot size and the detector’s received power are calculated. The results may be useful for underwater optical communication systems.
Keywords: Underwater optical propagation, flat-topped beam propagation, spot size, underwater optical communication
