Adaptive multi-beam X-ray ptychography.

Area of Science:

• X-ray imaging
• Nanotechnology
• Optics

Background:

• Ptychography is a key technique for nanoscale X-ray imaging using synchrotron radiation.
• Multi-beam ptychography offers faster imaging of larger areas compared to single-beam methods.

Purpose of the Study:

• To introduce an adaptive multi-beam ptychography method using two cascaded Fresnel zone plates.
• To enable adaptable spatial beam separation for diverse sample requirements.

Main Methods:

• Implementation of a novel optical scheme with two serially arranged Fresnel zone plates.
• Development of a method allowing seamless switching between single and multi-beam illumination.

Main Results:

• The proposed optical scheme allows for adaptive spatial beam separation.
• The method relaxes zone plate thickness constraints and is easy to implement.
• Simultaneous single and multi-beam illumination is achievable within one experiment.

Conclusions:

• Adaptive multi-beam ptychography enhances imaging speed and flexibility.
• This technique facilitates combining rapid, large-area surveys with high-resolution region-specific imaging.
