Laser-Based Camera Can Shoot Photos Around Corners

Laser-Based Camera Can Shoot Photos Around Corners

Femtosecond laser camera shoots pictures around corners…

A Professor at the Massachusetts Institute of Technology (MIT) has developed a new camera that can essentially see around corners.

By bouncing a laser around objects then capturing the tiny rays of light that bounce back, the camera is able to take pictures that are out of a person’s line of sight.

The device uses a femtosceond laser that shoots ultra short burst of light which last for one quadrillionth of a second. The laser is reflected of a wall to illuminate the scene around the corner, the camera then picks up the ‘echo’ of light that is bounced back from any objects in the scene.

To capture these tiny waves of light that bounce back, the camera snaps around a trillion frames a second.

A complex mathematical algorithm then computes the data and puts together the pieces of the puzzle to produce an image of what lay behind the corner.

Prof. Ramesh Raskar, head of the Camera Culture group at the MIT Media Lab who’ve been working on the technology for the last three years, likened the device to ‘x-ray vision without the x-rays.’

Prof. Raskar explained how the device could be used in search and rescue planning when the situation is too hazardous for rescue team to enter unaware of what lays inside; it could also see medical application as an endoscope that could take pictures where other endoscopes cannot reach.
