Abstract:
We present a novel Dynamic Depolarized Scattering method based on a tight confocal, zero
scattering angle, heterodyne scheme. The method is highly immune from parasitic multiple-scattering
contributions, so that it can operate with non-index–matched samples presenting large turbidity. It provides
measurements of both rotational and translational diffusion coefficients, the latter via number fluctuation
spectroscopy. In addition, the amplitude ratio between the two baselines for the fast rotational mode and
the slow translational mode can be used to determine the particles intrinsic birefringence.
