Camera Can See Around Corners

ananyo writes "Scientists at the Massachusetts Institute of Technology in Cambridge have created a camera that is able to record images of objects hidden behind walls. They fire a pulse of laser light at a wall on the far side of the hidden scene, and record the time at which the scattered light reaches a camera. Photons bounce off the wall onto the hidden object and back to the wall, scattering each time, before a small fraction eventually reaches the camera, each at a slightly different time. The camera captures this time-of-flight information and uses it to reconstruct an image of the hidden object (abstract)."

$32 for an article? Just think, a minimum wage worker has to work for over 4 hours to get access to that.
Somehow, I doubt that article is worth it.

If only someone invented some sort of laser that would allow me to see behind this paywall...
