You’ll be seeing this at the airport soon, I think. Everyone was concerned when they started saying they would install X-ray backscatter scanners at the security checkpoints, and those things couldn’t move. Now we’ve got a similar (to laypeople) technology in a mobile, pointable form. Sounds great!
These things work by emitting X-rays and analyzing the reflections; they add “which is how lobsters see through murky waters.” Really now. If lobsters had that kind of technology, they would have taken over by now. In any case, these things probably cost half a million dollars each and as such will be limited to military use if they ever even make it off this company’s website, but feel free to get a little bit more paranoid anyway.
