Camera Can See Around Corners

Posted by samzenpus on from the no-place-to-hide dept.

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)."

      Silly, that one was about a system at MIT that captured scatter at 2 x 10^-15 seconds resolution. This one is a system at MIT that captures at 2 x 10^-12 seconds resolution. Clearly they should be different stories on Slashdot.

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