Very interesting and also impressive. Intuitively, one might at first think that "seeing inside a closed room" implies "...without being seen yourself", however that is obviously not the case, since occupants of a room will hardly miss a giant beam of laser.
But then again that's not the point of this technique, and I can well imagine it being useful in rescue scenarios and such.
- MontagFTB 5y agoWould the technique not work with a laser outside the visible spectrum?
- _Microft 5y agoI expect this would work with infrared lasers as well.
- consumer451 5y agoIn which case a standard radar/laser detector made for cars would alert you, correct? [0] Tangentially, I always loved the story of the US Navy using consumer automotive radar detectors in fighter jets.

- _Microft 5y agoLaser detectors might be hard to find in living rooms but you could accidently detect it with the selfie camera of your smartphone. At least in the past, manufacturers cheaped out on this one and omitted the IR filter on it. You can try if that's the case by pointing an IR remote control at it from close up and see if it lights up when you press a button.
- ncmncm 5y agoIt would be hard to detect a microsecond-long laser flash even in visible light, never mind infrared.
