Abstract
In order to study the performance of circular array light source in underwater wireless light-emitting diode (LED) optical communication, the mathematical model of the relative intensity of illumination distribution was deduced choosing a circular array light source composed of 6 LEDs as the research object and based on the distribution model of a single LED illumination in the air. The actual underwater illumination distribution was measured with an illuminometer based on the dot matrix measurement method. The experimental data were analyzed. The results show that the intensity of illumination in the output port of the light source increases with the increase of the carrier signal frequency. The whole underwater illumination distribution of the light source is asymmetry. When the optical signal was transmitted to a certain distance, the illumination intensity tends to distribute more evenly in the light receiving plane.
