The photon-scattering imaging data of Liposyn II intravenous emulsion solution samples of different
concentrations and different thicknesses is reported and analyzed. The scattering Mueller matrix
element m11 data shows that the maximum number of multi-photon scatterings is an increasing
function of concentration and sample thickness.
Tissue is optically anisotropic and highly photon-scattering medium. It has long been treated as optically
diffusive medium in bio-medical applications. The diffusion equation of isotropic photon-density wave (PDW)
was widely applied to interpret the data of reflectance spectroscopy and biomedical imaging experiments. In
our recent transmission Stokes imaging experiment of the rat liver samples, the Mueller matrix elements were
measured and analyzed theoretically. The measured data of depolarization constant has shown that the optical
property is not perfectly diffusive. Based upon our recently developed theoretical model of anisotropic and
highly photon-scattering medium, the simulated results of anisotropy, photon-scattering and depolarization
property for the reflectance/backscattering experiment are reported.
Polarimetric imaging of Stokes vector (I, Q, U, V) can provide 4 independent signatures showing the linear
and circular polarizations of biological tissues and cells. Using a recently developed Stokes digital imaging
system, we measured the Stokes vector images of tissue samples from sections of rat livers containing normal
portions and hematomas. The derived Mueller matrix elements can quantitatively provide multi-signature
data of the bio-sample. This polarimetric optical technology is a new option of biosensing technology to
inspect the structures of tissue samples, particularly for discriminating tumor and non-tumor biopsy. This
technology is useful for critical disease discrimination and medical diagnostics applications.
