Claim 10:
11. An optical underwater communication method, comprising:
activating and deactivating light by one or more optical sources according to a first bit stream by a first transceiver and a second transceiver;
each of the first and second transceivers receiving light from another of the first and second transceivers by one or more sensor packages each comprising a plurality of photodetectors and, in response, provide i) an output voltage signal corresponding to photoelectron response of an incident photon on the one or more sensor packages, and ii) an output current signal in form of peaks corresponding to photoelectron response of an incident photon on the one or more sensor packages;
converting the output voltage signal and the output current signal to pulses associated with arrival of photons by a detector;
counting the number of pulses based on a predetermined timing sequence by the detector;
encoding a message by an encoder to be sent into the first bit stream, according to a predetermined communication protocol that is based on the predetermined timing sequence; and, decoding a message by a decoder into a second bit stream, according to the predetermined communication protocol that is based on the predetermined timing sequence.
