Birefringence and dichroism refer to variations in the real and                 imaginary parts of the refractive index with direction for anisotropic          media.  This research will measure birefringence and dichroism for              highly concentrated suspensions in order to gain information on the             microstructures than can form when such suspensions are subjected to            shear or electric fields.  Special emphasis will be placed on                   measurements as a function of the wave length of light because the              strong dependence of dichroism on the ratio of particle size to wave            length offers the possibility of probing structures of different                length scales in an anisotropic medium.  In particular, this may allow          characterization of structures in suspensions comprised of particles            of different sizes.                                                                                                                                             The research should lead to a more useful tool for characterizing               concentrated suspensions under processing conditions.  Applications             include ceramics casting and electrorheological fluids.
