Patent ID: 8045859

Claim:
A system for underwater data transmission, said system comprising: a photon source capable of providing a beam of electromagnetic radiation at a predetermined frequency with the beam capable of being pulsed to encode data of the underwater data transmission; an array of photo-receptors configured to collect the electromagnetic radiation; at least one integrator in communication with a plurality of photo-receptors of said array of photo-receptors, said at least one integrator capable of receiving signals from said plurality of photo-receptors corresponding to an intensity of said electromagnetic radiation collected by said plurality of photo-receptors with said at least one integrator integrating the intensity over said plurality of photo-receptors; and a signal processor in communication with said at least one integrator, said signal processor capable of receiving signals from said at least one integrator corresponding to the integrated intensity, said signal processor capable of determining the transmitted data based on an intensity-time track of the integrated intensity for the pulsed beam of electromagnetic radiation at the predetermined frequency; wherein each photo-receptor of said array of photo-receptors comprises an elongated lens having an optical opening therein to collect electromagnetic radiation in a direction aligned with a longitudinal axis of said opening; wherein each photo-receptor of said array of photo-receptors comprises a coating on an interior surface of said opening to absorb the electromagnetic radiation of the predetermined frequency.
