Paper Abstract

Tissues are optically anisotropic and highly photon scattering media. By using a simple ellipsoid model of bio-molecules with anisotropic distribution and using an effective mean-field theory, the principal anisotropic index of refraction nj(ω) and absorption extinction coefficient Kaj(ω), (j = x,y,z) are derived. The scattering extinction coefficient Ksj is calculated from our scattering depolarization theory of highly scattering bio-medium. The criterion of optical isotropy and anisotropy of a bio-medium is derived. The non-vanishing ▵n, ▵Ka and ▵Ks exist for medium with anisotropic molecules only. ▵Ks/<Ks> is larger for medium with higher density.
