We develop an optical wireless communication-based 2K real-time video surveillance system prototype with fieldprogrammable gate arrays. Using a 3-W blue light-emitting diode and an avalanche photo-diode, 20-m and 1.5-m realtime picture/video transmission with a high resolution of 1920 × 1080 pixels is implemented in free space and pure water channel, respectively. It indicates the good performance of the prototype, which is the first step to realize underwater visual monitoring in future human-robot interaction applications.

“…However, tethering significantly constrains the maneuverability and working range of the ROVs. In recent years, with the advancement of semiconductor and digital signal processing technologies, underwater wireless optical communication (UWOC) technology with high bandwidth and low latency has made tremendous progress in terms of data rates (up to ~Gbit/s) and transmission distances (up to hundreds of meters) [7][8][9]. It proved to be a promising technology in overcoming the limitations of conventional underwater acoustic communication for high-resolution multimedia streaming in the > REPLACE THIS LINE WITH YOUR PAPER IDENTIFICATION NUMBER (DOUBLE-CLICK HERE TO EDIT) < 2 order of Mbit/s across short transmission ranges (less than ~100 m) [10][11][12][13][14][15][16][17][18][19][20][21].…”

Real-time, dynamic, and visual monitoring of underwater scenes would become an important research topic with the development of underwater wireless optical communication (UWOC), autonomous underwater vehicle, and video fusion technologies. To this end, we developed a UWOCbased 2K real-time digital video surveillance prototype named AquaF-seer. Using a light-emitting diode and an avalanche photodetector based diffused line-of-sight UWOC system, realtime video transmission with a high resolution of 1920 × 1080 pixels is achieved over various channels, i.e., 1.5-m free space channel, pure water channel, pure water channel with 1.53-mL/s bubble-induced turbulence, pure water channel with 42.40-mL/s bubble-induced turbulence, simulated pure sea water channel, and coastal ocean water channel. Moreover, 46-m and 5-m video monitoring are implemented in free space and an outdoor diving pool. It indicates the reliability of the prototype, which is the first step to realize underwater visual monitoring in future humanrobot interaction applications.

“…ANKIND has made great efforts in exploring and utilizing marine space in the past few years, such as the development of marine oil, gas, and fishery resources. This has brought great economic benefits to human beings and has inflicted critical environmental issues to the oceans [1]. For example, undersea oil pipeline leakage has aggravated environmental pollution and deteriorated ecological environment; overfishing of coastal fishery resources has caused serious damage to marine resources.…”

Automatic subsea operations using real-time underwater optical wireless sensor networks are mooted as a new paradigm of underwater Internet of Things in this paper. To this end, we develop an underwater optical wireless sensor network prototype called AquaE-net, which consists of an optical hub and two sensor nodes with temperature, salinity, conductivity, and pH sensing capabilities. Clock synchronization is realized in AquaEnet, which paves the way for future underwater positioning and navigation. Moreover, real-time and bi-directional network communication with 100% packet success rates has been realized by AquaE-net in free space and turbid water in the harbor of the Red Sea at King Abdullah University of Science and Technology. This is the first step toward future effective marine environmental monitoring and marine resources exploration.
