We describe a modification of conventional dynamic light scattering (DLS) using a CCD camera as optical area detector. Scattered intensity autocorrelation functions are determined using both ensemble- and time-averaging. Therefore, the new setup allows for much shorter measurement times compared to conventional DLS. Our apparatus has been checked by investigating a dilute dispersion of polystyrene (PS)-microgel lattices in glycerol. The results agree well with DLS measurements using the standard setup. Further, we present data for ultraslow dynamical processes in highly concentrated nonergodic suspensions of PS-microgel lattices, where the new technique, due to its shorter measurement time and much better statistical accuracy as compared to conventional DLS, is most useful.
