Turbulent environment can highly affect the performance of free space optical (FSO) communication links. Therefore, how to obtain the turbulence intensity is a very important issue. The paper has shown the detailed analysis to calculate the log irradiance variance (σ2R) along with the experimental verification under an indoor laboratory controlled turbulence condition. This paper verifies the consistency...
This paper experimentally investigates the performance of different modulation schemes under the atmospheric turbulence conditions for free space optical communication links. The experiments were carried out in a dedicated and controlled indoor atmospheric chamber. The turbulence environment was created by introducing hot air, while the temperature profile was monitored throughout the chamber to maintain...
In this paper, we present the experimental results on smoke attenuation for a free space optical communication link. The smoke is generated in an indoor atmospheric chamber under the laboratory controlled conditions. Theoretical simulations are carried out in order to verify that the homogeneity of smoke inside the atmospheric chamber can be improved by increasing the link length. This is achieved...
