Dynamically reconfigurable framework for pixel-level visible light communication projector

We have developed the Pixel-level Visible Light Communication (PVLC) projector based on the DLP (Digital Light Processing) system. The projector can embed invisible data pixel by pixel into a visible image to realize augmented reality applications. However, it cannot update either invisible or visible contents in real time. In order to solve the problem, we improve the projector so that a PC can dynamically control the system and enable us to achieve a high-frame-rate feature by resolution conversion. This paper proposes the system framework and the design method for the dynamically reconfigurable PVLC projector.
