3D holograms built to help soldiers see rounds corners

Our eyes are wonderful organs, but even they are not able to see around corners – yet. The US's Defence Advanced Research Projects Agency is developing technology that aims to use holograms to allow soldiers to see what lies behind a wall or around the next bend. They have asked researchers to develop a computer program that can unscramble the light that bounces off irregular surfaces to create a holographic image of hidden objects. Engineers are developing new technology that will build up a holographic image of objects that are hidden out of sight behind obstacles or around corners. The system works by looking for the faint photons of light that are scattered by uneven surfaces.
