A Design of Image Transmission System Based on Visible Light Communication |
| |
| Abstract: | Now it is difficult to realize the image transmission based on the visible light communication because of low transmission rate.An image transmission system based on visible light communications is developed by studying the modulation principle of the high-brightness white LED and property of the photodetector.The light transmitter circuit and receiving circuit are designed in the system,as well as the software of image transmission and display are programmed.Eexperimental results verify that the system can comply characters and images communication in 2Mb/s from PC to PC,so it provides a reliable circuit proposal for the progress of high speed visible light communication. |
