介绍了一套可见光音频传输系统
该系统包含发射和接收两个模块。在发射模块端
用手机播放音乐
通过双音频线插头来输入音频信号;在接收模块端
利用C12702-11 APD模块把接收到的光信号转换成电信号
经过相关放大滤波等处理
使音响就可以播放出清晰的音乐。采用透镜聚光和平面镜反光可实现5 m以上的通信距离。
This paper introduces a new visible light/audio transmission system
which contains a transmitter module
a receiver module and optics. In transmitter module
a mobile phone is used to generate audio signals which modulate the LED light emission; In the receiver
a C12702-11 APD module converts the received optical signals into electrical signals which can make the sound broadcast clearly through the related amplifying and filtering processing. By using plane mirrors for light reflection and a lens to focus light
this system can achieve more than 5 m distance of communication.
