New tech is shrinking night-vision goggles down to the size of a nickel.
* Most night vision devices work by converting photons into electrons.
* This tech converts photons into an LED image.
It seems like nifty new apps for your smart phone appear every day. How about one that helps you see in the dark? Today, on Engineering Works! Listen to the podcast.
If you like war movies or just keep track of the news from Iraq and Afghanistan, you know something about night vision devices. They’re goggles, mated to a set of lenses and electronic gear that allow soldiers to see in the dark. They work pretty well, but they’re bulky, heavy and expensive.
Now, materials engineers have come up with something that could replace current night vision technology. And it’s everything the current technology isn’t. Small, light and cheap.
Most standard night vision devices work by converting photons, the subatomic particles that make up light, into electrons that hit a phosphorous screen and produce an image you can see. Making this work requires lots of electric power and heavy glass components.
The new idea uses a detector made up of layers of an organic semiconductor connected to an LED array. The LED gives you an image you can see.
The best part is that the device is about the size of a nickel. And it can be made of plastic instead of glass. The researchers say adding it to a cell phone should be really inexpensive. It also could be added to eyeglasses or automobile windshields.
We can’t see in the dark yet, so we’re going to leave for home before the sun goes down. See you next time.

Free apps for night vision or night enhancement software and £0.59p ones available on the iphone, whatever next?

me too man, can you imagine; night-vision goggles down to the size of a nickel and And it can be made of plastic instead of glass and it is really Inexpensive. It also could be added to eyeglasses or automobile windshields. dammn i want one too

I`m glad you posted this cause I was looking at night vision goggles today. Just pricing them out. The one I want is the scope style that can attach to a camcoder. With the technology changing the way it is ....the price could be right in the near future. Check this out.
