Role of scattering and birefringence in phase retardation revealed by locus of Stokes vector on Poincare sphere.

ABSTRACT:

Significance

Biological tissues are typically characterized by high anisotropic scattering and may also exhibit linear form birefringence. Both scattering and birefringence bias the phase shift between transverse electric field components of polarized light. These phase alterations are associated with particular structural malformations in the tissue. In fact, the majority of polarization-based techniques are unable to distinguish the nature of the phase shift induced by birefringence or scattering of light.

Aim

We explore the distinct contributions of scattering and birefringence in the phase retardation of circularly polarized light propagated in turbid tissue-like scattering medium.

Approach

The circularly polarized light in frame of Stokes polarimetry approach is
