Abstract

Coherent x-ray diffractive microscopy enables full reconstruction of the complex transmission function of an isolated object to diffraction-limited resolution without relying on any optical elements between the sample and detector. In combination with ptychography, also specimens of unlimited lateral extension can be imaged. Here we report on an application of ptychographic coherent diffractive imaging (PCDI) in the soft x-ray regime, more precisely in the so-called water window of photon energies where the high scattering contrast between carbon and oxygen is well-suited to image biological samples. In particular, we have reconstructed the complex sample transmission function of a fossil diatom at a photon energy of 517 eV. In imaging a lithographically fabricated test sample a resolution on the order of 50 nm (half-period length) has been achieved. Along with this proof-of-principle for PCDI at soft x-ray wavelengths, we discuss the experimental and technical challenges which can occur especially for soft x-ray PCDI.

Experimental setup for ptychographic coherent x-ray diffractive imaging of a fossil diatom: The illuminating wave field is confined by a small pinhole with a diameter on the order of 2 μm, before it impinges onto the sample after propagating over a distance z1 ≃ 1 mm. The sample, a diatom on a silicon nitride membrane, is scanned laterally through the beam on a rectangular grid while at each scan point a diffraction pattern is collected on a two-dimensional CCD detector placed at a distance z2 ≃ 0.49 m away from the sample. The same setup and measurement principle was then used in a second experiment to image a test pattern structured by nano-lithography.

(A) Optical micrograph of the fossil diatom sample. The area scanned by the x-ray beam is marked by a black frame. The dark stripe on the left side of the image corresponds to the edge of the silicon-nitride window. (B) Complex-valued ptychographic reconstruction of the object transmission function from the same diatom sample as shown in subfigure A. Color encodes phase (modulo 2π), brightness the amplitude as indicated by the colorwheel on the lower right. The positions at which the illuminating wave field (the probe) was centered during the scan are marked by white dots covering an area of 10.4(h) × 18.4(v) μm2. Note that also the edge of the silicon nitride window can be seen: Although the extension of the probe was on the order of 2 μm according to the full width at half maximum (FWHM) of the amplitude, the object is reconstructed far beyond the scanned area as marked by the scan positions. This is due to the relatively slow decay of the probe amplitude in the object plane (see section 4).

(A) Complex-valued object reconstruction (phase values modulo 2π) within the area that has been covered by the central and most intensive part of the probe wave field during the scan, roughly corresponding to the extension of the grid of scan points shown in Fig. 2B. (B) and (D) Detailed view of the amplitude (B) and phase (D) of the reconstructed object transmission corresponding to the marked square (side length 6 μm) in subfigure A. For the subregion shown here the phase has been unwrapped, i.e. it is shown without non-physical phase jumps due to wrapping phase values into an interval of width 2π. (C) Line profile of the phase perpendicular to the edge of the sample as marked by the white line in subfigure B. The red line marks a fit to the phase step with an error-function.

(A) Reconstructed amplitude of the Siemens star object transmission function. Towards the center the void areas in the innermost ring of the test pattern reach a width of 50 nm in angular direction and many of them can be separated from the filled stripes along their whole radial extension. (B) Reconstructed phase (in radians) of the area indicated by a square (side length 3 μm) in subfigure A. (C) Scanning electron micrograph of roughly the same region as imaged in the experiment. On the innermost side of each segmented ring the void stripes reach an angular width of 0.2 μm (third ring from center), 0.1 μm (second ring from center) and 0.05 μm (innermost ring).

(A) Complex-valued reconstruction of the probe function as obtained from the diatom dataset. Phase is encoded as hue, amplitude as brightness. The reconstructed probe wave is shown here back-propagated over a distance of 1.08 mm with respect to the plane of reconstruction. (B) Reconstructed illumination function as obtained from the Siemens star dataset. Here the probe was back-propagated over a distance of 1.36 mm. (C) Scanning electron micrograph of the exit surface of the pinhole used for beam confinement. (D) Typical background-corrected diffracted intensity (arbitrary units) collected for one scan point of the diatom dataset. The diffraction pattern extends to a full spatial period of 11 μm−1, or a corresponding real space pixel size of 45 nm. (E) Typical accumulated, background-corrected diffracted intensity collected for a scan point of the Siemens star dataset, using the same pinhole to define the illumination function as in the first experiment. Scale bars in subfigures A, B, C indicate 1 μm.

(A) Far-field geometry: For Fresnel numbers F = a2/(λ z1) ≫ 1 (with pinhole diameter a) the wavefront impinging on the sample is almost flat and the amplitude of the exit wave field well-confined. The field distribution at the detector in the far field shows no resemblance with the exit wave. There is no geometrical magnification of the exit wave field behind the sample and the width D1 of the exit wave’s FOV in the reconstruction plane is not related to the lateral size of the detector, but inversely proportional to its pixel width. (B) Effective near-field geometry: For Fresnel numbers F ≪ 1 the probe at the sample is nearly spherical and less well-confined in amplitude. This leads to a diffracted amplitude which can be interpreted as magnified near-field propagated object function (with the spherical part of the illumination removed). The extension D 1 = D 2 / M of the FOV in the sample plane is now proportional to the FOV width in the detector plane. (C) Vertical slice through the normalized reconstructed probe amplitude |P| for the Siemens star dataset. Red vertical lines mark the positions of the first side minima, within which 98 % of the intensity is located. (D) Vertical slice through the unwrapped reconstructed phase φ (P) of the probe function and the phase φ (S) of an ideal spherical wave S in paraxial approximation, emanating from the center of the pinhole and propagated over a distance z1.
