    Overcoming the Diffraction Limit Using Multiple Light Scattering in a Highly Disordered Medium
    (2011-07-06) Choi, Youngwoon; Fang-Yen, Christopher; Yang, Taeseok Daniel; Kang, Pilsung; Lee, Kyoung Jin; Dasari, Ramachandra R.; Feld, Michael S.; Choi, Wonshik
    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.
