Paper Abstract

The assessment of materials viscoelastic properties often represents a means of diagnosis or characterization of biological tissues and biomaterials. In this paper, we introduce a new optical method for the evaluation of dynamical properties of viscoelastic media. The approach is based on time-resolved spatial speckle imaging, using a continuous wave CW illumination and a standard CCD detector. We demonstrate that an estimation of viscoelastic properties is possible, by analyzing intensity and contrast profiles of scattering spot images acquired over multiple exposure times. The accuracy of this approach is evaluated using simulated tissue mimicking media having well known optical and dynamical properties.
