Free-space optical links
The potential for free-space laser links to deliver high-speed communications has been known for decades, but perennial problems have included the need for line-of-sight connectivity and the optical challenges of transmitting light over long distances in a turbulent atmosphere or adverse weather conditions. Aalyria believes that its use of adaptive optics is now able to overcome some of those challenges. Photo: Schott/Space Photonics.
