Hi, I'm trying to think up a way to shift IR rays into visible light spectrum so that the human eye can effectively see the IR image. Is it possible to do such a feat with something as simple as goggles made from a special material (e.g. anti-stokes pigments)?? If not possible with such simple devices, what is actually the most portable way of doing such a shift to visible light?? (something like night-vision goggles are too expensive and complicated... something more spartan) =D Thanks!
