ARRAY-BASED FREE-SPACE OPTICAL COMMUNICATION LINKS

摘要

Optical communication with a remote node comprises: transmitting at least one optical beam to the remote node; receiving at least a portion of at least one optical beam from the remote node; providing intensity information based on one or more signals from one or more optical detector modules in an array of optical detector modules detecting the portion of the optical beam received from the remote node; and controlling at least one optical phased array to steer the optical beam transmitted to the remote node based on intensity information received from the remote node.
