To begin with, this is an ingenious creation by the scientists at the Massachusetts Institute of Technology. With that note to the side, it is now time to proceed towards the creation: a camera capable of seeing around corners. How so? Its function is to construct a hidden object using scattered laser light, which bounces off walls and surfaces that are close to the obstructed object (in this case, something around a corner). “We are all familiar with sound echoes, but we can also exploit echoes of light,” said Ramesh Raskar, head of the Camera Culture Research Group at the MIT Media Lab. How the camera achieves this is by recording an image every two picoseconds, allowing the location of the object to me measured with extreme precision. An algorithm created by the team then processes the collected data and use it to construct an actual image of the object that is hidden — however this whole process takes an agonizing 10 minutes.
The scientists are striving to trim the time to just 10 seconds, where they make the inevitable suggestion for a true applicable use of the camera — the military. Still, in my mind there are much more useful places for a camera that can see around corners, but I’ll save that observation for another article. Video after the break. Via: Digital Trends
