The heterodyne near-field scattering (HNFS) technique for studying complex fluids such as colloidal systems was discussed. A different data reduction scheme was adopted which allowed the improvement in performance of the technique, at levels of sensitivity and accuracy much higher than those achievable with classical low-angle light scattering instrumentation. It was observed that this method also relaxes the requirements on the optical/mechanical stability of the experimental setup and allows for a real time analysis. Nonstationary samples, such as aggregating colloidal solutions, were also investigated, and their kinetics quantitatively characterized.

Abstract

The heterodyne near-field scattering (HNFS) technique for studying complex fluids such as colloidal systems was discussed. A different data reduction scheme was adopted which allowed the improvement in performance of the technique, at levels of sensitivity and accuracy much higher than those achievable with classical low-angle light scattering instrumentation. It was observed that this method also relaxes the requirements on the optical/mechanical stability of the experimental setup and allows for a real time analysis. Nonstationary samples, such as aggregating colloidal solutions, were also investigated, and their kinetics quantitatively characterized.
