Abstract
To obtain high-quality video images characterizing the ecological condition of the underwater marine environment in real time, it is necessary to create modern automated systems for accumulating and processing video information, which are aggregated from autonomous underwater devices equipped with special technical means of control, in particular, television cameras. Technologies for environmental monitoring using these systems make it possible to study the seabed for the presence of unfavorable environmental factors and foreign objects, to identify them, as well as to map the seabed topography in order to provide the coordination center with a full volume of data on the bottom ecological situation. All this requires high-resolution video transmission from autonomous underwater devices. The traditional hydroacoustic underwater systems for accumulating and processing video information are being replaced by open systems for its optical transmission and reception, based on laser technologies. An obstacle for the wider use of hydroacoustic fields is the low speed of video information transmission to surface objects. The article substantiates the expediency of using open optical communication systems to create high-speed underwater information telecommunications, among which the most preferable are laser systems that have sufficient broadband, which is necessary to ensure a high video stream speed.
