Chinese scientists develop a laser capable of 'seeing' hidden objects from a mile away

Scientists in China have developed a laser that can locate a hidden object from a mile away. Researchers hid a mannequin inside an apartment and fired a laser emitter at its location, determining the dummy's location by calculating how long it took photons to hit different parts of the room and travel back to the laser. The technology, known as non-line-of-sight (NLOS) imaging, could be utilized by the military to find enemy targets or rescue teams to find victims. It could also be beneficial in helping self-driving cars detect pedestrians and other vehicles from behind buildings. A team at the University of Science and Technology of China perfected the new technique.
