Research Progress of NLOS Optical Scattering Communication

摘要:

以紫外光通信为代表的非视距散射光通信是针对自由空间光通信的一种补充手段，在军事局域保密通信中得到广泛应用。阐述了散射光通信中的信道建模、调制解调等关键技术的研究现状及其工作原理，介绍了当前主流的光源、光检测器、光滤波器和光学天线等关键器件，并分析其优缺点及今后可能的发展方向。

Abstract:

NLOS optical scattering communication represented by ultraviolet optical communication is a complementary mean to free space optical communication, and has been widely used in military local secrecy communication. The research status and the principles of key technologies like channel modeling and modulation and demodulation technology are expounded. Besides, the key devices such as light source, photodetector, optical filter and optical antenna are introduced, and their relative merits are analysed. Their development trends are pointed out.
