Underwater OWPT is expected to significantly expand the field of underwater applications. To overcome the limit of long-distance underwater light propagation caused by a still relatively large propagation loss, a system that propagates the beam between underwater and the air with low loss is attractive. The use of a fly-eye lens system to suppress the influence of water waves has been proposed, and its effectiveness has been confirmed by simulation and experiment.
