Abstract :
In free space optical communication system, the characteristics of atmosphere affect laser transmission. These effects include absorption and dispersion of aerosol, dust, frog, rain, haze when laser beam through atmosphere. The laser power attenuation of the absorption and dispersion is introduced. Then the turbulence and its influence of flicker, bend and abruption are analyzed. At last the experiment research system and the test method are given. The experiments are carried out at the different air condition at the same time, in the different time at the same day and in the different visibility condition. The results are in accordance with theoretical analysis
