Nanotechnology Discovery May Lead Us To Low-Power Night Vision
 

Night vision technology is an essential tool in the modern world battlefield. The sad part is that it comes with some shortcomings. The conventional night vision goggles have a severely diminished view.

Their view has actually been compared to looking out of toilet paper tubes. The top of the line L-3 Ground Panoramic NVG’s which were also used in the Osama bin Laden raid also require an external source.

They are also very heavy and cumbersome. However with the recent breakthrough given by the Australian National University we could have NVG’s no thicker than a normal pair of sunglasses.

The Conventional NVG’s make use of cascaded secondary emission process which proceeds as follows:

1. The goggle objective first collects ambient low level and near-infrared light.

2. The photons are converted in to electrons and go down a plate studded with millions of tiny holes

3. As the electrons pass through the holes a chain reaction is set which releases hundreds of other electrons

4. These electrons hit phosphorescent plate which create a green tinted image

This whole process demands a lot of energy to generate the electrons required.The Australian team has made use of aluminum gallium arsenide nanostructures. They carry out the same process but without the vacuum tubes.

The new process also requires an external energy supply to work but will only require a fraction of a conventional NVG’s power.

It can also be produced as thin as film. This advancement will reduce the bulk and weight of future NVG’s. The Australian team has given their findings to the DARPA for further development.
