Title: Micro-rheology using multispeckle DWS  with video camera. Application to  rheological properties
Author: TISSERAND, Christelle; BRUNEL, Laurent; DIHANG, Hélène
Description: Microrheology is based on the Diffusing Wave Spectroscopy  method that relates the particle dynamics to the speckle field dynamics, and further to the visco-elastic moduli G' and G'' with respect to frequency. For the study of the rheological properties we show that the robust measurement of speckle correlation using the inter image distance can bring useful information for industry on viscoelasticity variations over a wide range of frequency without additional parameter.
