In the past few years, X-ray phase-contrast and dark-field imaging have evolved to be
invaluable tools for non-destructive sample visualisation, delivering information inaccessible …

ABSTRACT A fascinating way of generating speckle patterns is by interfering the weak fields
scattered by a disordered sample with the intense trans-illuminating beam. The resulting …

X-ray phase-contrast techniques are powerful methods for discerning features with similar
densities, which are normally indistinguishable with conventional absorption contrast. While …

摘要第四代同步辐射光源为多个研究领域提供了亮度和相干度更高, 性能更加优异的X 射线.
为了充分发挥这些光束的潜力, 需要精确的光束线装调和高质量的X 射线光学元件 …

A method is presented for the measurement of the phase gradient of a wavefront by tracking
the relative motion of speckles in projection holograms as a sample is scanned across the …

We demonstrate how the individual mirrors of a high-quality Kirkpatrick–Baez (KB) mirror
system can be aligned to each other to create an optimally focused beam, through …

The short wavelength of X-rays allows in principle the creation of focal spot sizes down to a
few nanometers and below. At the same time, this short wavelength and the resulting …

This thesis presents research on novel X-ray imaging methods that improve the study of
specimens with small density differences, revealing their inner structure and density …

In addition to the conventional way of using X-ray attenuation-contrast, there exist other X-
ray imaging modalities to acquire useful datasets about a material under investigation …

X-ray speckle-based imaging (SBI), one of them most recent phase-contrast imaging
methods, has received growing interest in the last years. Its simplicity, cost-effectiveness and …
