London - A camera that is fast enough to capture light pulses moving through objects was shown off by researchers, including one of Indian origin, at the TEDGlobal conference.
The so-called femto-camera can also take pictures around corners by collecting the tiny amounts of light that bounce around the scene.
Prof Ramesh Raskar showed a video of light travelling through a plastic bottle on stage.
The images may help develop new theories about how light travels.
“Einstein would have liked it,†the BBC quoted Raskar as saying.
Taking images was not his first thought for the camera, which was developed at the MIT Media Lab in 2010.
The different frames of the photographs were colour coded to give an impression of how light moves
“Initially I was obsessed with the camera seeing around corners and then I realised that we could use the data for pure visualisations,†he said.
He has discussed the idea with scientists from around the world, including those at Cern - the base for the Large Hadron Collider.
Other possible uses for the femto-camera include health imaging to offers views from inside the body without using x-rays.
An adapted device could also allow cars to “see†obstructions on the road ahead, while in disaster zones it could be used to see where people need help.
He admitted that it would be some time before the huge device made it out of the laboratory but to help it on its way he has released details about the technology behind it.
