• Expression of Target Optical Properties in Subsurface Polarization-gated Imaging 

    Nothdurft, Ralph; Yao, Gang, Ph. D. (The Optical Society of America, 2005-05)
    We examined the expression of target optical properties in subsurface polarization imaging under linearly and circularly polarized illumination. Reflecting, scattering, and absorption targets were imaged in tissue mimic ...
  • Imaging Obscured Subsurface Inhomogeneity Using Laser Speckle 

    Nothdurft, Ralph; Yao, Gang, Ph. D. (The Optical Society of America, 2005-12)
    We have developed a laser speckle imaging method to reveal obscured subsurface inhomogeneities that cannot be seen under incoherent illumination. Speckle images of a scattering object were generated under coherent ...
