Figure 2
Typical time-averaged two-dimensional scattering patterns (10000 frames added) for a dilute suspension of silica particles in water. The colored area depicts the region of interest selected for the calculation of intensity–intensity autocorrelation function and chosen q-values are indicated as rings. The inset depicts a typical speckle pattern in the low-q region in a single frame with an integration time of 0.5 ms. |
