Patent ID: 7953326

Claim:
An underwater communication system, comprising: a transmitter having a source capable of emitting electromagnetic radiation, and a diffuser having a substantially hemispherical surface, for transmitting the electromagnetic radiation at a rate of at least 1 Mbps along a plurality of radii defined by the surface for diffusing the electromagnetic radiation and disposed in a position surrounding a portion of the source for diffusing the electromagnetic radiation in a plurality of directions, and a receiver having a substantially hemispherical surface for receiving the electromagnetic radiation along a plurality of radii defined by the surface and being capable of detecting electromagnetic radiation passing at least 20 m through a high light scattering medium, such that the electromagnetic radiation can be received in substantially any direction; wherein, the transmitter and receiver are physically separated from each other, and wherein, the electromagnetic radiation includes electromagnetic waves of wavelength in the optical spectrum between 300 nm and 800 nm.
