Classification: CPC G  H | IPC G

Claim 0:
1. An optical underwater communication system, comprising:
a first transceiver and a second transceiver, each of the first and second transceivers including:
one or more optical sources configured to provide light activated and deactivated according to a first bit stream,
one or more sensor packages each comprising a plurality of photodetectors configured to receive light from another of the first and second transceivers 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,
a detector configured to i) convert the output voltage signal and the output current signal to pulses associated with arrival of photons, and ii) count the number of pulses based on a predetermined timing sequence,
an encoder configured to encode a message to be sent into the first bit stream, according to a predetermined communication protocol that is based on the predetermined timing sequence, and
a decoder configured to decode a message received into a second bit stream, according to the predetermined communication protocol that is based on the predetermined timing sequence.
