|Current dissertation explores the ways for vessels to communicate to each other using visible light spectrum. Through the course of this study a lot of practical work has been done - I built several different communication devices to transmit and receive data. I was able to achieve great understanding of the underlying physical processes behind electronics and programming logic, while practicing with building this hardware. The findings reveal various different aspects that must be taken into account in order to successfully build transmitter capable of being a competitor to current technologies used in the industry. Biggest advantage of this dissertation is in practical implementation of the ideas, since some of the earlier theoretical findings have been hard to execute in real life and some of the proposed software logic was not working as expected for the various reasons explained here. This paper will be useful to read for scholars trying to understand underlying problems behind visual light communication using ambient light or CMOS sensors, since both of these parts have been used in the hardware implementation. Those who would like to learn about communication logic and software/firmware programming will also find it interesting to see why some approaches work better than the others. Overall, I was able to successfully transmit a message via visible light and pointed out a roadmap for my future studies and physical hardware implementation.
