optical modem on nereus

New optical system tested

The modem for the newly developed optical communications system is mounted for testing onto the Nereus, WHOI's new hybrid remotely operated vehicle (HROV). The system, devised by a team led by WHOI Senior Engineer Norman E. Farr, will allow near-instant data transfer and real-time video from un-tethered ROVs and autonomous underwater vehicles (AUVs) outfitted with sensors, cameras and other data-collecting devices to surface ships or laboratories. The device will be used for undersea investigations of anything from the acidity of water to indentifying marine life to observing erupting vents and seafloor slides to measuring numerous ocean properties. In addition, the optical system would enable direct maneuvering of the vehicle by a human.
