Laser camera can see around corners

Researchers have designed a special camera set-up that can see around corners without using angled mirrors.

The system works by bouncing high-speed laser pulses off “non-reflective” surfaces into the hidden area. The trajectory of the pulses is carefully controlled, and an extremely sensitive detector is used to record the pulses as they bounce back in the direction from which they were fired. By measuring the exact time taken for the pulses to shoot around the corner and return, the system can build up an image of the hidden area.
