Now You See, Now You Don't (VIDEO)

Caption

Now you see it, now you don't. The University of Central Florida Pegasus symbol, visible in infrared, disappears as it enters the visible light spectrum that the human eye sees. UCF NanoScience Technology Center associate professor Debashis Chanda led a team of researchers who developed this technique that uses nanotechnology to preferentially control absorption of light to hide images and information in plain sight. Further, in the infrared domain the image can appear, disappear or change based on external stimuli, like voltage. The technology has potential applications in anti-counterfeiting, security and camouflage.
