Latest Patents

Xu is credited with 1 patent, titled “Beaconless Laser Alignment with Beamforming.” The invention describes an agile beaconless laser beam alignment technique intended to establish or improve the reliability of optical communication links while reducing scanning time.

In the described approach, a transmitting station first scans a non-optical beam across an initial search field using a specified pattern. It then scans an optical field across a refined search field, which is determined at least partly from alignment information identified during the first scan. The technique may support links between stations, including satellite-to-satellite communications.
