This paper first analyzes the basic physical characteristics of the mist and fog attenuation empirical models are summarized . On this basis , combined with the single scattering theory , transport theory of multiple scattering , and the use of the discrete ordinates method for solving the transport equation . Focus on the multiple scattering of laser to spread decay rate in the fog , a more in line with the practical application of the fog decay mode . Gaussian beam attenuation in the fog discussed , and the numerical results were compared with the results of the plane wave . Finally, laser slant path propagation mist and fog environment of wireless optical communication system are discussed , proposed a solution for laser slant path propagation . Based on the physical and mathematical models of wireless optical communication system , the fog of wireless optical communication system receiver signal - to - noise ratio .
