New Cell Phone App: Night Vision

Facebook X LinkedIn Email
GAINESVILLE, Fla., May 7, 2010 — A University of Florida engineer has crafted a nickel-sized imaging device for night vision that uses organic LED technology similar to that found in cell phone or laptop screens. But 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. “Really, this is a very inexpensive device,” said Franky So, a professor of materials science and engineering at the university. “Incorporating it into a cell phone might not be a big...Read full article

    infrared
    Infrared (IR) refers to the region of the electromagnetic spectrum with wavelengths longer than those of visible light, but shorter than those of microwaves. The infrared spectrum spans wavelengths roughly between 700 nanometers (nm) and 1 millimeter (mm). It is divided into three main subcategories: Near-infrared (NIR): Wavelengths from approximately 700 nm to 1.4 micrometers (µm). Near-infrared light is often used in telecommunications, as well as in various imaging and sensing...
