Optical Wireless Underwater Communications: New Technology for Distance Increase

水下通信对于自然资源的开发至关重要（例如，渔业和近海石油）， 海洋监测（例如，气候、污染、地震），以及搜索和调查（例如，沉船，地雷， 映射）。水下传输面临着各种挑战，无论是在无线电频率， 声学无线或光学无线/自由空间光学（FSO）。 FSO提供了以非常高的速率进行传输的手段，具有不同的应用，例如无人驾驶。 水下航行器（UUV）到UUV的链路。然而，这样的高数据速率传输仅在非常低的传输速率下是可能的。 短的距离.原因之一是发射机和接收机需要建立一个点对点 空间对齐的连接，以获得良好的检测性能。 拟议研究活动的目标是通过整合智能运动来克服这一挑战 敏捷传感器技术公司开发的带有FSO传感器的控制平台， 远距离传输的能力。新的集成系统将在不同的水中进行测试 条件，以验证其性能改进时，与原来的系统相比。

Underwater communication is crucial for the exploitation of natural resources (e.g., fisheries and offshore oil), ocean monitoring (e.g., climate, pollution, earthquake), and search and survey (e.g., shipwrecks, mines, mapping). The underwater transmission faces various challenges, regardless if done in radio frequency, acoustic wireless, or optical wireless/free-space optical (FSO). FSO provides the means of transmitting at very high rates, having different applications, such as unmanned underwater vehicle (UUV)-to-UUV links. However, such a high data rate transmission is possible only at very short distances. One of the reasons is that the transmitter and receiver need to establish a point-to-point spatially aligned connection for a good detection performance. The goal of the proposed research activity is to overcome this challenge by integrating an intelligent motion control platform developed by Agile Sensor Technologies with FSO transducers in order to provide the capability of transmitting at longer distances. The new integrated system will be tested under different water conditions to verify its performance improvement when compared with the original system.
