A hybrid algorithm for wave-front corrections applied to satellite-to-ground laser communication
Laser communications hold accurate data rate for ground satellite links.
The laser beam is transmitted through the atmosphere. The clear-air turbulence induces a number of phase distortions that damage wave-front. Adaptive optics (AO) treats wave…
