Figure 7
(a) Flat-field image of the synchrotron beam at 12 keV acquired using a fibre-optic-coupled CCD detector showing beam uniformity. The figure also shows the horizontal and vertical profile plots of the image grey values and its histogram. (b) Flat-field-corrected image of the beam in high-resolution CCD and its grey value histogram. The figure also shows horizontal and vertical profile plots of image grey values and its histogram. |
