The idea of being able to see through walls and around corners just became very real with a new study coming out of the University of Wisconsin-Madison and the Universidad de Zaragoza. The researchers at these universities have made strides in this new technology by means of methods of classical optics.

The practical applications of such a technology are vast. In the medical industry, it could allow for physicians to see internal parts of the body without the time factor of the current technology (ie. capsule endoscopy). Another application is for imaging in the defense and intelligence industries. It will allow for military personnel to better scope areas and intelligence agencies to locate people of interest.
