Focused beam profiles of 1D FZPs measured using the differential-phase-contrast knife-edge scan test. Open circles represent the scan data, black lines represent the moving averages of three scan points. (a) Apodization FZP, scan step 3.125 nm, and (b) conventional FZP, scan step 6.25 nm. The dwell time was 0.1 s and the X-ray energy was 8 keV. |
