Abstract
A novel free space optics transceiver is disclosed comprising at least one light source, at least one photodetector, corresponding positioning means that can independently adjust the position of the light source and the photodetector, and a controller that can send and receive alignment frames conforming to a communications protocol to and from a remote optical transceiver and can use information in the incoming alignment frames from the remote optical transceiver to appropriately adjust the position of the light source and the photodetector thereby maximizing the received power of light signals sent by the remote optical transceiver. Also, an alignment method is disclosed wherein the controller continuously adjusts the positions of the light source and the photodetector until a light signal is acquired from a remote optical transceiver. Then, the incoming alignment information is used to adjust the light source position to achieve bi-directional communication with the remote optical transceiver.
