TECHNOLOGY

Researchers at the Massachusetts Institute of Technology have built a camera that can see around corners, by bouncing bursts of laser light off doors or walls.
The system works like a periscope. But instead of mirrors, it uses ordinary walls, doors or floors; instead of light, the camera is equipped with a femtosecond laser that emits bursts of light so short that their duration is measured in
quadrillionths of a second.
