Multiscale X-ray imaging using ptychography.

Area of Science:

• X-ray imaging
• Coherent X-ray sources
• Materials science

Background:

• Ptychography and other imaging techniques are increasingly successful at third-generation X-ray sources.
• Wider availability of coherent X-rays drives development of complementary imaging methods.
• Limited integration of these complementary techniques has been observed.

Purpose of the Study:

• To present a flexible framework integrating established imaging techniques, particularly ptychography.
• To address variable requirements in synchrotron experiments.
• To enable seamless transitions between low- and high-resolution imaging modes.

Main Methods:

• Integration of full-field microscopy for wide fields of view (>mm).
• Application of ptychography for high-resolution imaging (<100 nm).
• Implementation at the I13 Coherence Branchline at Diamond Light Source.

Main Results:

• Demonstration of a framework for flexible application of imaging techniques.
• Ability to obtain low-resolution images of entire samples.
• Capability to zoom into specific regions of interest with higher resolution.

Conclusions:

• The developed framework enhances the utility of synchrotron-based imaging experiments.
• It allows for adaptable imaging strategies, from broad overviews to nanoscale details.
• This integration improves the efficiency and scope of X-ray microscopy applications.
