【摘要】：逆向调制光通信是自由空间光通信的一种特殊形式,它的系统包括两个不对称的终端:询问端和逆向调制端,询问端由光发送机和光接收机组成,逆向调制端由逆向调制装置组成。逆向调制光通信可实现逆向调制端对询问端的单向通信,它具有视场角大、功耗低、体积小等优点,适合于小平台工作环境。与传统自由空间光(FSO)通信相比,逆向调制光通信系统无需复杂的跟瞄系统,但通常只能完成逆向调制端对询问端的单向通信。如果要实现逆向调制光通信的全双工通信,可以考虑从调制方式和系统设计上进行研究。本文从调制方式出发提出了一种单光源全双工逆向调制光通信方案,仿真分析了方案的信号传输过程,实现了室内近距离逆向调制单光源全双工光通信实验,验证了方案的可行性。
[Abstract]:Reverse modulation optical communication is a special form of free space optical communication. Its system consists of two asymmetric terminals: the interrogator and the reverse modulator, and the interrogator consists of an optical transmitter and an optical receiver. The reverse modulation end is composed of reverse modulation device. Reverse modulation optical communication can realize one-way communication between reverse modulation end and inquiry terminal. It has the advantages of large field of view, low power consumption, small volume, etc. Compared with traditional free-space optical communication, reverse modulation optical communication system does not need complex tracking and pointing system. But usually only the one-way communication between the reverse modulation end and the interrogator can be completed. If the full duplex communication of the reverse modulation optical communication is to be realized, In this paper, a full duplex reverse modulation optical communication scheme with single light source is proposed, and the signal transmission process of the scheme is simulated and analyzed. The experiment of indoor full duplex optical communication with single source of close range reverse modulation is carried out, and the feasibility of the scheme is verified.
