Applying the Polarization Memory Effect in Polarization-gated Subsurface Imaging
Nothdurft, Ralph; Yao, Gang, Ph. D. (The Optical Society of America, 2006-05)Polarization memory is a well established phenomenon occurring when circularly polarized light propagates in turbid media of larger particles. Recent studies have demonstrated that the circularly crosspolarized imaging can ... -
Effects of Turbid Media Optical Properties on Object Visibility in Subsurface Polarization Imaging
Nothdurft, Ralph; Yao, Gang, Ph. D. (The Optical Society of America, 2006-08)We studied the effectiveness of using polarized illumination and detection to enhance the visibility of targets buried in highly scattering media. The effects of background optical properties including scattering coefficient, ... -
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 ...
