Seeing Around Corners or Through Tissue

A new holographic technique can do amazing things by bouncing lasers of opaque objects.

"It's like we can plant a virtual computational camera on every remote surface to see the world from the surface's perspective," Willomitzer said.

For people driving roads curving through a mountain pass or snaking through a rural forest, this method could prevent accidents by revealing other cars or deer just out of sight around the bend. "This technique turns walls into mirrors," Willomitzer said. "It gets better as the technique also can work at night and in foggy weather conditions."
