New Film Offers Cheap Night Vision
A new 7 layered film based on OLED technology offers a cheap night vision solution for almost any device…
Night vision goggles are great for seeing in the dark, however having the gift of sight after nightfall comes at a price – conventional night vision goggles are heavy, bulky and extremely expensive.
But now, a DARPA funded research at the University of Florida has adapted a technology usually found in flat-screen OLED displays, to create a thin film that can turn any infrared signal into visible light – thus enabling night vision on the cheap.
Cheap Night Vision Technology
Current night vision goggles use several thousand volts of electricity to maintain a vacuum within the device. But the new film technology requires no vacuum, instead uses 7 layers of OLEDs to convert infrared light to the visible light spectrum.
As the light enters the film, a small charge approx 3-5 volts amplifies the signal as it passes through each additional layer. Once the IR passes all the way through the film layers, it’s converted in to visible light.
The night vision tech being just a few microns thick, will go some way in eliminating the tunnel vision and altered depth of field associated with binocular-style goggles that sit inches away from the eyes.
And although the current prototype only covers one square centimeter, researchers say that the new technology could integrate cheap night vision tech into car windshields, cell phone cameras and even regular eyeglasses within the next 18 months.
