摘　　要：利用LED高频率闪烁的响应特性,设计了一种基于LED可见光波分复用的音频传输演示仪。波分复用是让不同波长的可见光同时加载不同信号,通过同一信道传输信息的通信技术。本装置实现了可见光通信技术和波分复用技术的结合,可以大大提高可见光通信的效率。装置亦可用于课堂演示。The response characteristics of LED high frequency flicker is used to design an audio transmission demonstration instrument based on LED visible wavelength division multiplexing.Wavelength division multiple-xing is a communication technique that allows different wavelengths of visible light to simultaneously load dif-ferent signals and transmit information over the same channel. This device realizes the combination of visible light communication technology and wavelength division multiplexing technology,which can greatly improve the efficiency of visible light communication.The device can also be used for classroom presentations.
