Abstract

This paper focuses on evaluating the performance of two aperture averaging methods used for compensating the effects of the air turbulence in free space optical (FSO) communications. These methods are based on using a concentration lens and spherical concave mirrors (SCM). The preliminary experimental results show that the quality of the received signal in terms of the Q-factor and the scintillation index is moderately improved when employing a lens in comparison to SCM for all turbulence regimes. However, these results were obtained with different collection areas and focal points. Therefore, a more rigorous approach using lens and SCM with the same aperture diameters and focal lengths needs to be adopted to ensure conclusive results.
