Abstract

The free space optical (FSO) communications link performance is affected by the atmospheric turbulent. In this letter, we experimentally investigate environment effects on the FSO link under different turbulence conditions. We show that the measured refractive index structure parameter Cn2, which demonstrates the scintillation strength, varies proportionally with the ambient temperature and the sun elevation angle. We experimentally investigate changes in Cn2 with respect to the sun elevation angle and other key parameters that affect the link performance under turbulence and show that higher elevation angle lead to stronger intensity fluctuations at the receiver for a given constant temperature. Moreover, we show that Cn2 behaves proportionally as an exponential function of the elevation angle.
