Wasn't sure whether to open this here or in the weapons forum.

Anyway, IMO this is a pretty cool development if it could be used to reliably find IED's at a safe distance, taking away another terror weapon. The article also says it could be used to find pollutants in the atmosphere.

The new device actually uses one laser to create a second laser out of thin air at the target area, which then beams information right back to the first laser.

Science Daily source


"We are able to send a laser pulse out and get another pulse back from the air itself," said Richard Miles, a professor of mechanical and aerospace engineering at Princeton, the research group leader and co-author on the paper. "The returning beam interacts with the molecules in the air and carries their finger prints."

Is anyone else thinking the Norway spiral?
Maybe a test of some sort?
Gets you thinking...

The picture in the article shows a much smaller, table-top sized device. But who knows? "They" always say what we get to see is years behind what is really being worked on or even deployed.
