Spy Camera Takes 3D Photos in Almost Complete Darkness

DailyMail.co.uk reports that spies operating under the cover of darkness might find that their job is about to get easier as U.S. scientists have developed a camera that can take photographs of objects and people that are only very dimly lit.

The camera works by reconstructing 3D images from photons reflected from barely visible objects.

The technology could be used in next generation spy cameras or to treat eyes that are easily damaged by bright light.

HOW DOES THE CAMERA WORK?

  • The camera works by scanning an object using low-intensity pulses of laser light.
  • Each pulse of light is fired until a reflected photon is recorded by a detector in the camera.
  • Using the algorithm, each illuminated location is matched to a pixel in the image that is created.
  • The time it takes for photons from the laser pulses to be reflected back from the object and read by the detector, provides information about the depth of the object being examined.

Researchers from MIT have managed to create sharp images of dimly lit objects using photons, which are elementary particles that are not composed of smaller particles.
