Abstract

During a 24 month period beginning in early 2008, Lincoln Laboratory conducted two free-space optical communication experiments designed to test the ability of beam diversity, symbol encoding, and interleaving to reduce the effects of turbulence-induced scintillation. The first of those exercises established a 2.7 GHz link over a 5 km horizontal path; that test was followed by a flight demonstration of a long-range air-to-ground link. This article presents a small sample of the power-in-fiber data obtained from those experiments
