Paper Abstract
The study of the interaction of polarized light with biological materials such as human tissue has
applications in medical diagnosis and medicine. Polarized light that is reflected or transmitted
through biological specimens can also be used to detect and identify biological and chemical
threat agents. The determination of the silent foot prints of the chiral properties of the biological
materials on scattered polarized light, is the basis for these investigations. The polarization states
of electromagnetic waves which in general are elliptical, are represented by its Stokes vector.
Scattered light is completely characterized by the 4 x 4 Mueller matrix that relates the scattered
Stokes vector to the incident Stokes vector. It is of primary importance to identify which of the
sixteen elements of the Mueller matrix for reflected and for transmitted light are most sensitive
to the chiral properties of the biological materials. The explicit analytical dependence of these
specific elements of the Mueller matrix, upon the angles of incidence and scatter, upon the
wavelength and upon the type of chirality has the potential to provide experimentalists with
guidance in determining the optimum use of optical polarimetric scatterometers to detect and
identify biological materials through their chiral properties.
