수중 LED 통신 시스템 연구

Abstract

In underwater environment, a sonar is mostly used as a communication tool. However, its speed is not fast enough to transfer large data such as image. To speed up the data transfer speed, the LED light is used as a communication tool in this paper.

The overall structure of the system is introduced including the control system of the LED lamp, light transmission and receiver system. Finally, experiments were performed on the developed underwater communication system in sea water and fresh water and results are described.
