The camera that can see round CORNERS: Gadget identifies hidden shapes by tracking changes in light waves and ‘echoes’

  • Computer scientists at University of Bonn developed the camera system
  • It lets users see round corners without using mirrors, like a periscope
  • System uses diffusely reflected light from a laser to reconstruct the shape of objects outside the cameras’ field of view

Crude contraptions using mirrors to see round corners have been used for centuries as spying devices, as well as at war.

But now scientists have developed a camera system that lets users see round corners using laser light.

By tracking diffusely reflected light, the invention reconstructs the shape of objects outside of the field of view.

Researchers at the University of Bonn and the University of British Columbia in Vancouver, came up with the array of devices.

A laser is shone on a surface, such as a wall, and serves as a source of scattered light, as well as the source of information.

In a demonstration, a laser is shown shining on a white wall, while a camera watches the scene. All it can see initially through the lens is a ‘spot’ of light.

This graphic shows the set-up of the equipment. The light source (red) and camera (field of view marked in blue) both look at a white wall. The objects the experts want to reconstruct (green box) are hidden and are only accessible through indirect reflections off the diffuse wall
