Abstract

Optical telecommunications will be the next technological step in Earth-to-space communication. However, propagation of an optical beam through the irregular atmosphere results in significant distortion of the signal, necessitating correction schemes for Earth-to-space communications. Conventional approaches to correct distortions that are based on natural or artificial guide stars are useful in astronomical imaging, but have practical difficulties or are not adequate to correct the distortions important for Earth-to-space optical links. Then we proposed a system, which employs an orbiting spacecraft with a bright laser reference source and a relay mirror, can provide essentially perfect scintillation correction.
