Figure 1
Full-field TXM images of the central region of a spoked star test pattern acquired using a zone-doubled Fresnel zone plate with an outermost zone width of 20 nm at (a) 9.0 keV and (b) 10.0 keV photon energy. The smallest pattern spokes of 30 nm width are clearly resolved. (c) Fourier ring correlation plot demonstrating a spatial resolution of 17 nm in the TXM images when considering a 1/2-bit SNR threshold curve.  [article HTML]
