Optical Signals and Prospects Towards Multimedia in Underwater Wireless and Mobile Communication

Light may be suitable for underwater wireless communication of multimedia data. However, current optical solutions face obstacles due to directionality and wavelength-dependent absorption and scattering. Here, we propose a conceptual design using differential signalling and a concave, multiple-aperture array of photodetectors. This combination could increase the field of view, enhance link adaptability, and introduce redundancies, supporting remote monitoring and data-collection with mobile robots in offshore operations.
