| 4/29/2011 | | Free space optical communication is the most growing communication because it is easy to install and has a high speed because the signal is transmitted in the air. So that will introduce the atmospheric affect in the optical wave propagation. Atmospheric turbulence causes fluctuations in both the intensity and the phase of the received signal. So we need to study the effect and the limitation if we introduce a free space optical communication system with dual wavelength

INTRODUCTION Free-space optical communication (FSO) is an optical communication technology that uses light propagating in free space to transmit data for telecommunications orcomputer networking. "Free space" means air‚ outer space‚ vacuum‚ or something similar. This contrasts with using solids such as optical fiber cable or an optical transmission line. The technology is useful where the physical connections are impractical due to high costs or other considerations. Free-space optical communication
