BBC : Researchers at the Weizmann Institute of Science in Israel have developed a breakthrough technique of seeing around corners and through semi-translucent surfaces using incoherent, natural light instead of coherent, laser light or x rays. By keeping track of the phase of an incoming light beam and refocusing the scattered light at a desired location, their spatial light modulator undoes the scattering that makes objects opaque. Such a technique could be used in Earth-based astronomy and deep-tissue imaging. Their results appear in Nature Photonics.
