Comment on Night vision glasses: nanocrystals allow direct vision into infrared

Comments

These night vision glasses don't exist and the use of the phrase 'allow direct vision' is misleading seeing as they're using high powered lasers to see the blue shift. This lab has only made a nanocrystal that might enable this technology one day.

The fact that everyone in the linked video is wearing funny looking green glasses is misleading, those are just safety glasses.

These types of news blips are depressingly common in developmental science. I can guarantee they're just looking to secure more funding.

Thank you. I was wondering where they got the extra energy from, as IR is less energetic than visible. Did they use two photons to get one (ie, reduce the intensity)? No. They use a separate light source.

So the advantage here over current tech is that you are able to see the visible also, it seems. That is, you're looking through glass and getting all of the visible plus enhanced IR.

Also, it wouldn't preserve the direction of photons. So you couldn't just put a sheet of something in front of your eyes, you'd have to have a lens to focus the incoming image on a screen, and another lens for your eyes to focus on the screen.

If I could, I would fund them. Sounds pretty good. I've seen worse ideas receiving funding.
