Well it’s not exactly what we think of as laser scanning in that it does not create a 3D point cloud, but from Homeland Security’s point of view it is a lot more useful. Imagine being able to detect a certain type of molecule from 50 meters – mind boggling.
Genia Photonics has invented what they call the Picosecond Programmable Laser scanner with the capability “of detecting every tiny trace of any substance on your body, from specks of gunpowder to your adrenaline levels to a sugar-sized grain of cannabis to what you had for breakfast.”
Expect to start to see this technology being used next year. I think the world just got a lot safer.
