摘　　要：针对移动应用平台间进行较短距离的直接通信,设计了一种基于以太网和无线激光传输的通信链路系统。该系统使用直接调制的方式将以太网发出的电信号调制到光波上,将携带信息的载波激光束聚焦、对准发送至接收设备;接收设备将采集到的信号进行解调,由光信号还原出发送方输出的电信号,经以太网传输至接收端,实现信号的双向传递;该系统可实时、大容量、高速地传输语音、数据、视频和图像等信号,且通信质量稳定可靠,保密性和安全性能优良。测试结果表明,该系统能较好地在大气间进行实时高速地数据通信,满足移动应用平台间的保密需要。A system based on Ethernet and wireless communication link of laser transmission is designed for the directed communication between mobile application platforms carried a short distance. The electrical signals emitted by the Ethernet are modulated to optical wave over direct modulation. The modulated optical signals are focused to be the laser beam and then aligned to the receiving device; receiving device demodulates the collected signal and optical signals are restored into electrical signals. The electrical signals are sent to the reception side via Ethernet. This sys- tem can realize bi-directional high-capacity high-speed real-time signal transmission of voice, data, video and image signals with reliable communication quality, excellent privacy and security. Test results showed that the system can achieve high-speed data communication radio channel to meet the need for confidentiality between pairs of mobile ap- plication platforms.
