摘要
在深入研究自由空间光通信(FSO Free Space Optical communication)和国内外引信光学装定技术现状的基础上,对实现引信激光装定系统的编码调制技术进行了理论研究,给出一个低功耗、便携式引信激光装定系统设计方案,系统采用半导体激光器作为光源,采用PIN光敏二极管作为光接收器件,通过RS信道编码、PPM调制及激光驱动电源控制,实现信息在激光载体上的高速率大气传输,最后给出系统的实验结果,探讨了引信激光装定技术的应用前景。
On the basis of studying technology of FSO(Free Space Optical communication)and domestic、foreign fuze optical set,this paper analyzes techniques of encoding and modulation in theory and then a low power dissipate and portable fuze laser setting system was designed.The system adopts a semi-conductor laser as optical source and a PIN photodiode as optical receiver to transfer information in atmosphere via RS encoding、PPM modulating and laser driving circuit control.Finally,the experimental results and the application foreground are presented.
