Combining Information Display and Visible Light Wireless Communication

This paper opens up an unforeseen and intriguing application area of our recent pioneer work of temporal psychovisual modulation: wireless optical communication. It is demonstrated how a high-speed optoelectronic display functions as a 2D array of optical transmitters and at the same exhibits conventional images as usual. 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.
