2D speckle pattern. a Single split-pulse scattering pattern. b Sum of 2.5 × 103 scattering patterns. The brown circular area corresponds to the beamstop, which was masked in the data analysis process. c Signal of single (blue), double (green) and triple (yellow) photon events in a 22 by 22 pixel region of interest (shown by the yellow square in a). d Azimuthally integrated intensity of the summed scattering patterns collected from the static sample (green). Red circles denote the integrated intensity collected from the dynamic gold sample at two detector positions
