MIT Femtosecond Laser Camera Shoots Pics Around Corners, No Periscope Required | Popular Science: "The camera works by incorporating complex computer algorithms with blasts from a femtosecond laser that issues ultra-short bursts of light lasting just one quadrillionth of a second. Those intense light bursts charge forward and illuminate a scene – even a scene around the corner from the source – sending photons bouncing around the area. Some of those photons make it back to the camera, which uses aforementioned complex computer mathematics to rebuild the scene around the corner, pixel by pixel.

Professor Ramesh Raskar, head of the Camera Culture group at MIT’s Media Lab, equates the technology to X-ray vision, but instead of going through an obstacle the camera uses light to go around it. "
