Abstract
An apparatus is described which uses directly modulated InGaN Light-Emitting Diodes (LEDs) or InGaN lasers as the transmitters for an underwater data-communication device. The receiver uses automatic gain control to facilitate performance of the apparatus over a wide-range of distances and water turbidities.
Claims20
A system to optically transfer seismic data through an aqueous medium, comprising:
- a retrieval device comprising:
- a first optical transmitter to transmit light;
- a first optical receiver;
- one or more optical detectors to sense a relative angle of a second optical transmitter of an ocean bottom seismic (“OBS”) node;
- and
- at least one controller configured to:
- select, based on a signal from the one or more optical detectors of the retrieval device, an anode in a multiple-anode photomultiplier tube;
- and
- align an angular field of view of the first optical receiver with the second optical transmitter of the OBS node.

A method of optically transferring seismic data through an aqueous medium, comprising:
- transmitting, by a retrieval device comprising a first optical transmitter and a first optical receiver, light;
- sensing, by one or more optical detectors of the retrieval device, a relative angle of a second optical transmitter of an ocean bottom seismic (“OBS”) node;
- selecting, by at least one controller of the retrieval device, based on a signal from the one or more optical detectors of the retrieval device, an anode in a multiple-anode photomultiplier tube;
- and
- aligning, by the at least one controller of the retrieval device, an angular field of view of the first optical receiver with the second optical transmitter of the OBS node.
