We demonstrate that polarization modulation of an illumination beam can effectively control the spatial profile of the light transmitted through turbid media. Since the transmitted electric fields are completely mingled in turbid media, polarization states of an illumination beam can be used effectively to control the propagation of light through turbid… (More)
We present a novel optical method exploiting multiple scattering to achieve sub-wavelength focusing and imaging using visible light. The evanescent near-field information are controlled by or transferred into far-field components by scattering from disordered nanoparticles.
We report the enhancement of signal and penetration depth in 2-D imaging in optical coherence tomography by suppressing multiple scattering via complex wavefront shaping. Up to 92% enhancements of the penetration depth were observed for a highly scattering sample.
