From: Probing ultrafast foam homogenization with grating-based X-ray dark-field imaging
Transmission and dark-field images of a heated foam target. (a) Shows a transmission image with a gradient due to the pump laser used for TNSA. (b) shows the dark-field image with two ROIs where unheated foam is present. The striped horizontal line seen in (a) and (b) is caused by the non-sensitive gap in the detector. (c) shows the distribution of dark-field values before the correction in these ROIs. Shown in (d) is the distribution of dark-field values in the same ROIs after the dark-field image is background corrected.
