This Camera Can Track Moving Objects Around Corners

Scientists at Heriot-Watt University in Edinburgh, Scotland have created a camera that can locate and track objects around corners. The camera shoots laser pulses at the floor near a corner, then analyzes how the light spreads and bounces off of an object concealed around that corner. It launches these pulses 67 million times per second and records the average of the results after three seconds. The camera can show an object's position and follow its movement, but only gives a rough outline of its shape. In the future, researchers hope that this technology will prove useful for drivers, emergency responders, and people who must venture into dangerous locations.
