With the developing of the technology of optical communication, more and more research institute focus on the project that Wireless optical communication system. Laser in the atmosphere of the transmission properties is the key problem of the optical communication system. Laser in the atmosphere of the transmission characteristics of the process of cable and optical transmission is completely different. Laser in atmospheric transmission will meet the absorption of atmosphere, scattering, reflection and turbulence and hot dizzy wait for a phenomenon. The phenomenon of the further research to the laser communication system design has a very important influence.This paper based on the laboratory project " key technology research of space optical communication ". In the thorough research in all kinds of laser atmospheric transmission characteristics, and on the basis of developing a atmospheric optical transmission software. For the future of the atmospheric optical communication system more in-depth study lay the foundation. Based on the analysis of the influence of atmospheric optical transmission, The main selection for absorbing phenomena in beer-lambert law as the foundation of the theory model, For scattering phenomenon is according to different atmospheric conditions select Rayleigh scattering and mie scattering theory model, For laser through the process of atmospheric turbulence based mainly on the rove isotropic turbulence theory evenly. Using the information of the basic theory of optical analysis. Using discrete method of analysis. The computer simulation is a series of random phase screen simulation turbulent structure. Given the laser field thought atmospheric turbulence disturbance. Given the analysis of the atmospheric optical communication system the specific effect.During simulation of the basic information of the optical are based on sampling theorem and Fourier analysis theory and The advantage of using computer data calculation. Using the combination of C++ and matlab programming method, we given Atmospheric transmission of laser in process of effective simulation.
