Subsurface Imaging with NIR Light Using Polarization Gating

摘要：

　　In this paper,a numerical study with the near infrared(NIR)laser light and polarization gating is used to show possible contrast improvement of the spherical inclusion hidden in the turbid medium.Inclusion has the same refractive index and scattering properties as surrounding medium but slightly higher absorption.Approach is based on time-resolved reflectance measurements and selection of photons with arc-like trajectories using polarization gating technique.Numerical studies performed for two turbid media,typically used to mimic biological tissues,reveal that coaxial setup of laser and detector is not suitable for detection of photons with arc-like trajectories.As well,the contrast improvement in ballistic-photon imaging strongly depends on the single-scattering phase function.
