This study proposes a novel high-speed RGB+IR projector which introduces sensing in invisible wavelengths and can manipulate visible display images based on its sensing results. Two mounted DMDs control RGB and IR images simultaneously. Our original optics aligns the images coaxially while maintaining a compact configuration and high-power projection.
