摘要
设计了基于单光源的全双工可见光通信系统,实现了可见光兼具照明和通信的功能。利用“猫眼”逆向调制器对下行光信号进行两次调制,将上行信息调制到下行光信号上并反射回主动端。实验表明,单光源可以实现全双工可见光通信链路,并且使上下行链路的通信互不干扰,通信效果良好。
Abstract
A full duplex visible light communication system based on single light source is designed, which realizes the functions of both visible light illumination and communication. The cat eye reverse modulator is used to perform remodulation on the downlink optical signal, and the uplink information is modulated onto the downlink optical signal and reflected back. The experimental result shows that the system with single light source can realize full duplex visible light communication and make the communications between the uplink and the downlink independent, and the communication effect is good.
