Hemispherical optical dome for underwater communication [PDF]
Laser Communication and Propagation through the Atmosphere and Oceans VI, 2017 For many years, acoustic systems have been used as the primary method for underwater communication; however, the data transfer rate of such systems is low because sound propagates slowly through the water. A higher throughput can be achieved using visible light to transmit data underwater.
