(a) Single-pulse speckle pattern collected using ePix100 under the low illumination conditions. The red lines mark the region of interest (ROI) used for the droplet analysis (see text for details). The average number of photons per pixel inside the ROI is kavg = 0.036. Plots (b) and (c) show part of the ROI before and after the droplet analysis, respectively. |
