Underwater communication system for deep sea divers using visible light

Abstract

This paper discusses a novel idea for transmission of voices in real time, underwater so that the system can be used by the deep sea divers for both lightning and data transfer applications simultaneously. Experiments were performed using white light, green and blue light respectively to transfer voice in real time in a water tank and the graphs were obtained. Based on the comparison study, we make recommendations for the selection of the right colour of light for communication efficiency in specified underwater environments.
