Visible Light Communication Based on Temporal Psychovisual Modulation


We report on our research in an intriguing application area of our recent pioneer work of temporal psychovisual modulation: visible light wireless communication. It is demonstrated how a high-speed optoelectronic display functions simultaneously as a 2D array of optical transmitters and a conventional visual output device. At the receiving end, digital cameras can download data via the optical MIMO link while user(s) can work and read the display as they are accustomed. The said unification of information display and wireless optical communication is made possible by psychovisually based image processing.
