Cameras on mobiles could use lasers to see THROUGH walls

You may be impressed with the incredible capabilities of cameras on today's smartphones. But according to imaging experts, that's nothing compared to what may be around the corner. Researchers claim cameras of the future could have the ability to see through walls with the help of lasers, potentially leading to a new generation of'spy phones'. In this article by The Conversation, Daniele Faccio, a Professor of Quantum Technologies at the University of Glasgow, and Stephen McLaughlin, Head of the School of Engineering and Physical Sciences at Heriot-Watt University, examine the technologies that could underpin a larger revolution of camera technology. You might be really pleased with the camera technology in your latest smartphone, which can recognise your face and take slow-mo video in ultra-high definition.
