Figure 1
Schematic representation of the three geometries used within the proposed protocol. The elements annotated on the figure are beam-shaping slits, a central beam stop (CS), a Fresnel focusing zone plate (FZP), an order-sorting aperture (OSA), a cardboard diffuser, the sample and a detector. (a) Geometry suited for parallel-beam holography, generating wide field-of-view and low-resolution images. (b) Geometry suited for near-field ptychography, producing intermediate to small field-of-view and sub-micrometre-resolution images. (c) Geometry suited for scanning transmission X-ray microscopy producing images within a wide range of fields of view and resolutions and suited for far-field ptychography for small field-of-view and high-resolution images.
