"This device can convert any infrared image into a visible image and would weigh no more than a pair of eyeglasses," said Franky So, a scientist at the University of Florida who describes his new night vision technology in a recent article in the journal Advanced Materials that was funded in part by advanced technology powerhouse DARPA.
Most night vision devices today use massive amounts of electricity -- often several thousand volts, according to So -- and heavy, glass lenses that maintain a vacuum to make the night come alive. So's device takes a radically different turn, replacing glass with thin plastic, eliminating the vacuum and using energy-efficient, organic LEDs.
So does this by using technology borrowed from flat screen TVs. Infrared light enters the film and is detected by the first of seven separate layers, which generates a slight electrical charge. Additional electrical energy -- about three to five volts -- amplifies that signal, which is then converted back into visible light.
