Fig 3: Phase contrast image
(a) X-ray image of a gold test pattern taken in phase contrast with 30 nm minimum feature size showing the imaging capabilities of the TXM. The field of view is 14 µm2 and the scale bar is 1 µm (b) Blow-up of the indicated region showing the resolved features which can be estimated from the image to be 40 nm. Analysis of the modulation transfer function confirms a resolution of 40 nm.
