Figure 5
(a) Series of speckle patterns measured from a static sample at P04 (PETRA III). The speckle forming the structure factor peak exhibits a single-frame speckle contrast of about 30%. The inset shows a microscope image of the static sample. (b) Waterfall plot of intensity over 1000 speckle patterns with a 0.12 s single frame exposure. The data were taken from the structure factor ring in (a). (c) Intermediate scattering function from the data shown in (b). For comparison, correlation functions with relaxation times τ = 1000 s and τ = 100 s are shown, highlighting the high stability during the experiment. |
