How to see round CORNERS using lights: Camera identifies hidden shapes

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. Computer scientists have developed a camera system (pictured) that that lets users see round corners without using a mirror. Researchers at the University of Bonn and the University of British Columbia in Vancouver, came up with the array of devices.
