Figure 7
Image taken at 8 keV with star pattern features tapering to 30 nm in (a) absorption mode and (b) Zernike phase-contrast mode. (c) Image of a star pattern with features tapering to 24 nm taken at 8 keV in absorption mode. (d) RPSD analysis of (c). RPSD was created by rolling-off the image edges across a width of 40 pixels to avoid discontinuities for the Fourier transform. |
