Abstract: Disclosed are an underwater optical communication aiming method and apparatus. The underwater optical communication aiming apparatus may include an optical communication module configured to transmit and receive laser beams and a plurality of acoustic modules spaced apart from one another at given intervals, disposed around the optical communication module, and configured to find a direction or relative distance of a counterpart light source under water. A direction of the optical communication module may be aimed at a counterpart light source found through the acoustic module in order to communicate with the counterpart light source by using the optical communication module.

Abstract: Disclosed herein is an underwater visible light transceiving terminal, which is capable of easily receiving a visible-light signal transmitted from a certain direction, through an optical-fiber assembly composed of a plurality of optical fibers that are radially arranged, and which is capable of delivering data, sent from a main communication station, in several directions in the form of a visible-light signal in the water through the optical-fiber assembly, thus allowing a submarine or a submergence robot to effectively receive the visible-light signal.
