Nano Night Goggles

University of Southern California and the University of Texas have been experimenting with nano technology to achieve night vision capabilities. Nano technology is used to create “quantum dots”, which can detect infrared radiation at the same levels as sensors in the night vision goggles currently used by the military.

The quantum dots consist of different materials and rely on different physical properties for detecting infrared than existing sensors. Each dot has a core of indium arsenide surrounded by gallium arsenide and an indium-gallium arsenide alloy. A single dot is about 20 nanometers in base size and about 4 nanometers in height.

The use of nano technology in this manner can conceivably drive the cost of the night vision goggle down to about one-third the price. Night vision goggles will be affordable to all!
