Abstract
A projection display system includes a visible light source coupled to project a visible image onto a screen. An infrared (IR) light source is coupled to project a non-visible IR image onto the screen. The non-visible IR image on the screen is independent of the visible image on the screen. The visible image and the non-visible IR image are overlapped and are displayed simultaneously on the screen.
