Laser System Delivers Video Underwater

May-19-18 A new laser-based system allows underwater video to be sent without wires.

Typically, underwater remotely-operated vehicles (ROVs) must be tethered to the receiving source in order for the operator to see the video feed.

To let ROVs swim more freely, a student-teacher team from KAUST has developed a wireless, optical sensor that relies on converting the video to rapid pulses emitted by a green laser diode. These pulses travel through the water to form a connection with a 450-nanometer blue laser photodiode receiver, which translates the data into video in real time. The transmitter is also able to adjust for the clarity of the water, speeding or slowing the transmission to maintain video quality.
