The underwater optical communication is getting more popular day by day. About 71 %
of the Earth’s surface is covered with water and 96,5 % of this covered area is the oceans.
During the past thousand years, human have never stopped exploring the oceans. Most of
the comprehensive ocean explorations made underwater world and it became a great
interest to the scientific, industrial and military societies. Underwater communication
makes the underwater explorations possible. Bidirectional and secure underwater
communication is a very challenging task even with nowadays technology, because the
methods for wireless communication in air, do not work in water. In this thesis, Radio
Frequency, acoustic and optical communication methods for underwater environment are
inspected by comparing advantages and disadvantages of the methods. In addition to this,
one transmitter and one receiver of underwater optical communication electronic system
and one laryngophone system prototype is designed and constructed. The directional
optical communication between one transmitter and one receiver has been successfully
demonstrated on the field and error free audio communication has been successfully
accomplished at a distance of 60 meters
