American scientists have shown a prototype camera that can photograph objects that are hidden behind an obstacle.
As a result of shooting are obtained, however, not the usual photos, and 3D-projection of the objects.At the moment the camera is able to “photograph” only objects of small size.
To get a picture using a laser. Its rays are reflected from the object, which is located within sight fixed by the object. Photons initially reflected from your subject, then the object, and eventually returned to the “camera”.Then, gathering data from all of the photons and calculating the amount of time they spend on it to reach the target and back, the camera creates 3D-model of the object.
