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 component whose strength is measured using polarization gating. The measured phase of the ballistic light is inverted using filtered backprojection algorithm and the reconstructed real refractive index for an optical fiber hidden in a scattering media is presented.
