Figure 2
Example for holographic data acquired with the dual-beam FZP. The images show full frames of the LAMBDA detector. (a) Raw image of the two holograms on the detector. Between these, the primary beam leaks through the central stop, but the intensity of this peak is below the saturation rate of LAMBDA. The black dots on the outer edge of the illuminated areas are caused by imperfections in the dFZP. (b) Flat-field corrected holograms obtained via dynamic flat-field correction. |
