Franky So, a University of Florida engineering researcher, has developed a nickel-sized imaging device that uses organic light-emitting diode technology (similar to that found in cell phone or laptop screens) for night vision.

Unlike night vision goggles, which are heavy and expensive, the device is paper-thin, light and inexpensive, making it a possible add-on to cell phone cameras, even eyeglasses, once it is enlarged.

The imaging device replaces the conventional vacuum tube with several layers of organic semiconductor thin film materials. The structure is simple: a photodetector connected to an LED.

So said other applications could include night vision technology for car windshields, or even for standard glasses to use at night.
