Abstract
We demonstrate experimental measurement of phase of the ballistic and near- ballistic component of light transmitted through scattering media. This is done through measurement of transport of intensity of the ballistic compone nt whose strength is measured using polarization gating. The measured phase of the ballistic light is inverted using filtered backprojcction algorithm and the reconstructed real refractive index for an optical fiber hidden in a scattering media is presented.
