Diffusing acoustic wave spectroscopy.
We have developed a technique in ultrasonic correlation spectroscopy called diffusing acoustic wave spectroscopy (DAWS). In this technique, the motion of the scatterers (e.g., particles or inclusions) is determined from the temporal fluctuations of multiply scattered sound. In DAWS, the propagation of multiply scattered sound is described using the diffusion approximation, which allows the auto...

In this chapter we describe a recent development in dynamic light scattering (DLS), which may ultimately have a significant impact on the range of problems that can be addressed and on the types of system that can be studied. We discuss diffusing-wave spectroscopy (DWS), which extends DLS to very highly multiple scattering media. This technique extends the analytic power of DLS to opaque sample...
متن کاملDiffusing-wave spectroscopy
Since its invention about a decade ago, dynamic multiple light scattering has found many applications in various areas of soft condensed matter science. It has become a particularly important quantitative to~1 in colloid physics because of its applicability to systems containing very high concentrations of scatterers, and its extreme sensitivity to small motions. Recent advances of this techniq...
متن کاملPulse wave analysis with diffusing-wave spectroscopy.
Hypertension is a major risk factor for cardiovascular disease and thus at the origin of many deaths by e.g. heart attack or stroke. Hypertension is caused by many factors including an increase in arterial stiffness which leads to changes in pulse wave velocity and wave reflections. Those often result in an increased left ventricular load which may result in heart failure as well as an increase...
متن کامل1 . 3 Diffusing - Wave Spectroscopy
This section focuses on recent work on temporal fluctuations of the intensity of multiply scattered light which are caused by motion of the scatterers. While parts ofthe underlying physics had already been discussed in 1983/84 [85, 86], dynamic multiple scattering of light was introduced by the work on calibrated colloidal latex particles in aqueous suspensions [29, 30, 87], and has since rapid...
