DESIGN ANALYSIS OF A COMPENSATION TECHNIQUE IN FSO COMMUNICATION SYSTEM TO MITIGATE ATMOSPHERIC TURBULENCE EFFECT

To mitigate the impact of atmospheric turbulence on free-space optical links using compensation techniquesincluding adaptiveoptical (AO) system as advanced technique.Itsthree main components have remained constant: a wavefront sensor to measure distortion, a wavefront corrector to compensate for the distortion and a control system to calculate the required correction and necessary shape to apply to the corrector.The main goal of any adaptive optical system is to show a phase correction in the arriving wavefront that converts the distorted wave front into a plane wave.We computeStandard deviation of the atmospheric tilt,DM Stroke,The residual phase variance,the turbulence strength for different telescope apertures
