We report that disordered media made of randomly distributed nanoparticles can be used to overcome the diffraction limit of a conventional imaging system. By developing a method to extract the original image information from the multiple scattering induced by the turbid media, we dramatically increase a numerical aperture of the imaging system. As a result, the resolution is enhanced by more than 5 times over the diffraction limit, and the field of view is extended over the physical area of the camera. Our technique lays the foundation to use a turbid medium as a far-field superlens.National Institutes of Health (U.S.) (P41-RR02594-24)Korean Science and Engineering Foundation (R17-2007-017-01000-0)National Research Foundation of Korea (2011-0005018)National Research Foundation of Korea (2011- 0016568)Korea.
