A system developed by researchers at Stanford University can essentially see through walls using a laser with a super-sensitive photon detector and an algorithm that can reconstruct three-dimensional (3D) hidden scenes based on the movement of photons.

The system was able to reconstruct shapes concealed by 1-inch-thick foam.

Said Stanford's Gordon Wetzstein, "A lot of imaging techniques make images look a little bit better, a little bit less noisy, but this is really something where we make the invisible visible.”

The system is useful for large-scale applications where there are few ballistic photons, like the navigation of self-driving cars in the rain, or the satellite imaging of planets with hazy atmospheres.
