The dynamics of polystyrene latex spheres [650 A radius] suspended in glycerol have been studied using the techniques of dynamic light scattering in the single scattering limit and diffusing wave spectroscopy in the multiple scattering regime using a charge coupled device [CCD] camera as our detector. Our experiments, which investigated suspensions of various concentrations [0.001</=0</=0.075], extended over length scales ranging from q = 0.00015 A to q = 0.00071 A and spanned three orders of magnitude in the time domain [0.1 s to 100 s]. Our measurements of the temporal fluctuations of the scattered intensity indicate that the dynamic behavior of our samples can be well characterized with intensity autocorrelation functions both in the single scattering limit and the multiple scattering regime.
