Comprehensive Design Criteria and Analysis of Laser Communication System for Underwater Vehicles

Underwater vehicles are utilized in various fields, such as exploration, submarine research, and industrial applications. However, underwater communication is often a formidable challenge because conventional communication technologies are ineffective for underwater vehicles. Therefore, laser communication systems for underwater vehicles are receiving more and more attention. This paper presents a novel approach by investigating comprehensive design criteria and analysis of laser communication systems for underwater vehicles. Firstly, the basic principles and working mechanisms of underwater laser communication systems are explained. Then, the main factors affecting system performance and design criteria are discussed in detail. These criteria include communication distance, data rate, power consumption, optical properties of the underwater environment, and system stability. Different laser modulation techniques and communication protocols are also evaluated. The paper also focuses on simulation, channel diversity, and test methods that can be used to assess the performance of laser communication systems in different underwater environments.
