Figure 2
Homodyne (a–d) and heterodyne (e–h) correlations for latex spheres obtained for four q values. Correlations are plotted as a function of t. Error bars are calculated from formulae valid for small intensities. Fits corresponding to equation (8) are also shown, together with fluctuation times τ1 and τ2. Note that the last reliable result was obtained for q = 6.7 × 10−3 Å−1 and that τ2 ≃ τ1. |
