Improved Quality Video Transmission by Optical Channel from Underwater Mobile Robots

Search for minerals in the continental shelf of Russia, monitoring gas and oil pipelines, inspecting the underwater parts of the vessel, solving the problem of navigational uncertainty under water is impossible without the use of underwater mobile robots that allow transmitting control data, telemetric information and video images of improved quality in real time. In the interests of solving these tasks, a prototype of an underwater optical channel for transmitting information and control data, as well as enhanced submarine images with a speed of 10 … 100 Mbit/s, has been developed and the requirements for its technical parameters have been formulated. The limiting distances for transmitting information in different types of waters for an underwater transmission system with a budget of 45 dB have been determined.
