Confocal full-field X-ray microscope for novel three-dimensional X-ray imaging.

Area of Science:

• X-ray microscopy
• 3D imaging techniques
• Materials science

Background:

• Traditional X-ray imaging methods often lack high resolution for 3D structural analysis.
• Developing advanced microscopy techniques is crucial for detailed material characterization.

Purpose of the Study:

• To develop and demonstrate a novel confocal full-field X-ray microscope for 3D imaging.
• To enable high-resolution, non-destructive 3D visualization of specimen internal structures.

Main Methods:

• Utilized a unique 'sheet-beam' X-ray illumination system.
• Employed a full-field X-ray microscope with its optical axis perpendicular to the sheet beam.
• Achieved 3D imaging through linear translation of the specimen.

Main Results:

• Successfully generated virtual sliced images of a specimen.
• Demonstrated the capability for three-dimensional observation via specimen translation.
• Performed feasibility tests at SPring-8, observing metallic inclusions in artificial diamond.

Conclusions:

• The developed confocal full-field X-ray microscope is a viable novel 3D X-ray imaging method.
• This technique allows for detailed 3D structural analysis of materials.
• Further applications in materials science and other fields are anticipated.
