Photographing Objects Out Of Sight

Scientists Develop Camera That Captures Objects Out of Sight

Fox News Latino | December 6, 2015

Scientists at Heriot-Watt University in Edinburgh have developed a camera that can locate objects around blind corners and detect their movements, a study published in the journal Nature Photonics said.
The system could provide tracking in real time of objects hidden from direct sight in different situations of daily life, such as surveillance and the prevention of automobile collisions.

The camera could be used in disaster zones, or for cars moving around corners. Source:

Genevieve Gariepy, Francesco Tonolini, Robert Henderson, Jonathan Leach and Daniele Faccio. Nature Photonics (2015). doi:10.1038/nphoton.2015.234. [Abstract: The ability to detect motion and track a moving object hidden around a corner or behind a wall provides a crucial advantage when physically going around the obstacle is impossible or dangerous. Previous methods have demonstrated that it is possible to reconstruct the shape of an object hidden from view. However, these methods do not enable the tracking of movement in real time. We demonstrate a compact non-line-of-sight laser ranging technology that relies on the ability to send light around an obstacle using a scattering floor and then detect the return signal from a hidden object within only a few seconds of acquisition time. By detecting this signal with a single-photon avalanche diode (SPAD) camera, we follow the movement of an object located a metre away from the camera with centimetre precision. We discuss the possibility of applying this technology to a variety of real-life situations in the near future.])>
