One answer is to develop X-ray vision. A more mundane approach is to use a mirror. But if neither are an option, a group of scientists led by Genevieve Gariepy have developed a state-of-the-art detector which, with some clever data processing techniques, can turn walls and floors into a \u201cvirtual mirror\u201d, giving the power to locate and track moving objects out of direct line of sight.<\/p>\n<p>The shiny surface of a mirror works by reflecting <a href=\"http:\/\/m.phys.org\/tags\/scattered+light\/\" rel=\"tag\">scattered light<\/a> from an <a href=\"http:\/\/m.phys.org\/tags\/object\/\" rel=\"tag\">object<\/a> at a well-defined angle towards your eye. Because light scattered from different points on the object is reflected at the same angle, your eye sees a clear image of the object. In contrast, a non-reflective surface scatters light randomly in all directions, and creates no clear image.<\/p>\n<p>However, as the researchers at Heriot-Watt University and the University of Edinburgh recognised, there is a way to tease out information on the object even from apparently random scattered light. Their method, <a href=\"http:\/\/www.nature.com\/articles\/doi:10.1038\/nphoton.2015.234\">published in <i>Nature Photonics<\/i><\/a>, relies on laser range-finding technology, which measures the distance to an object based on the time it takes a pulse of light to travel to the object, scatter, and travel back to a detector.<\/p>\n<p><a href=\"http:\/\/phys.org\/news\/2015-12-amazing-camera-corners-video.html\" target=\"_blank\">Read more<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>How can a person see around a blind corner?
