'''Diffusing-wave spectroscopy''' (DWS) is an optical technique derived from [[dynamic light scattering]] (DLS) that studies the dynamics of light scatterers in the case of strong multiple scattering.

It has been widely used to study colloidal suspensions, emulsions, foams, gels, and biological media, etc. If carefully calibrated, DWS allows the measurement of particle motion in a complex medium, andfrom thenwhich itsthe [[rheology]] of the complex medium can be extracted ''via'' ([[Microrheology | microrheology]]) theory.
