At the Massachusetts Institute of Technology have developed a device that allows you to shoot objects outside the zone of direct vision. It is based on the reconstruction of images based on the reflection from the wall, ultra-short laser pulses. How this works can be seen in the video. The development can be widely used in various fields.
