Abstract

This presentation explores the possibilities of using AO, which is widely applied to the correction of turbulent phases in astronomy but is now used in free-space communications (FSO). Optimal controllers have been demonstrated to be a helpful way of improving the error budget on extremely demanding AO systems in astronomy. Still, no recent study shows the full benefits of implementing an optimal control AO in a working FSO communication system. Here, we present our first results after implementing a closed-loop AO system in the Universidad de los Andes laboratory that allows us to test real-time controllers and implement the AO correction directly to FSO communication systems.
