摘　　要：蓝绿激光水下通信技术涵盖了光学工程、通信工程、海洋工程等众多技术领域,需要多学科、多专业的技术有效综合。目前,国内外的研究主要集中在调制/解调和编/解码技术方面,以及水下信道的模型建立与模拟。水下光信道的数学物理模型,主要用"蒙特卡洛"方法模拟,也取得了一定的成果,但是,建立较为理想的水下光信道模型尚需时间;调制/解调技术和编/解码技术,要多借鉴星地激光通信研究中的一些方法,随时把最新技术引入水下光通信领域,加以改进、吸收;重点发展微型及小型耐压水密舱技术,有利于蓝绿激光水下通信组件的多平台移植;借鉴水声学领域的研究成果;并期待光学、声学及电磁学等领域的新理论、新方法和新试验的突破。The technology of underwater communication using blue-green laser covers many technical areas, such as optical engineering, communication engineering, and ocean engineering, which indicates that this technology is an efficient combination of multi-disciplines and technologies. The current researches mainly focus on the technologies of modulation/demodulation and coding/ decoding, as well as the modeling and simulation of the underwater communication channels. The mathematical and physical models of underwater laser communication channels are mainly simulated with Monte Carlo method, which have resuhed in some progresses. But it is still far away from the perfect models. Investigations on the technologies of modulation/demodulation and coding/decoding mostly employ the similar methods used in satellite-earth laser communication together with updated related technologies and neces- sary modifications. The technologies of significant development of micro-/small-type pressure-proof watertight compartment are im- portant for the component transfer of underwater blue-green laser communication system. The promising breakthrough can be expected with employing research results of hydroacoustics and the upcoming new theories, methods, and experimental designs in optics, acoustics, and electromagnetism.
