Seeing around corners has always been a nut that has just been too hard to crack, until now…
An MIT research team have developed a camera that can do just that by using a new form of photography called Femto-photography which exploits the finite speed of light and analyzes ‘echoes of light’.
The project has a long way to go but promises potential applications in fields ranging from medical imaging to transport. Check out the team’s video explaining how to camera works:
‘A laser pulse that lasts less than one trillionth of a second is used as a flash and the light returning from the scene is collected by a camera at the equivalent of close to 1 trillion frames per second.’
