I wonder what other applications this could support. Better colour displays, where a monochromatic LED is converted to one of R, G and B?
I think they said it right there Military applications. And if price is low enough, you could use it to enable people to do outdoor work at night when it's less hot in arid/hot areas with less risk of injury (due to better vision), etc.
Reading the article it hints at the reality that it doesn't actually work like passive glasses as it implies. the blueshift effect happens because they're using a laser to excite the crystal and it later emits the shifted light, but you have to pump a lot of energy in for that output. Simple conservation of energy implies this won't work for normal night vision applications, instead they want to shine a laser spotlig…
It doesn't sound like you need to illuminate the scene with a laser spotlight, it sounds like they will input a small amount of laser light into the crystal film on the glasses. The externally sourced IR photons will combine with the internally generated laser photons and emit a visible frequency photon.
The amount of laser energy pumped into the crystal film will probably be proportional to the amount of energy you want out of your "screen", i.e. brightness
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.
>They hope within five years they will have a prototype of their invention that will allow the production of affordable, lightweight night-vision glasses, as simple to wear as a pair of sunnies.
>Professor Neshev said they are discussing their next steps with DARPA, a research and development arm of the US Department of Defence.
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.

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.
