Abstract

Free Space Optics (FSO) is a data transmission technology using an optical beam going through the atmosphere. This communication technology has several indisputable advantages but also disadvantages. The one of the disadvantages are the thermal turbulences. This paper deals with the artificial thermal turbulences which affect the optical beam going from the commercial FSO head. The new against articles with similar topic is that this paper describes the turbulent effects spatially and not point wise as is often the case. At the same time this paper shows 3D modelling of turbulent effect on the FSO optical beam. The aim of the measurement was a demonstration of effects of the thermal turbulences and comparison the clear and turbulent atmosphere. The measurement was realized in four distances because the shape of optical beam was different in different distances.
