Area of Science:

• Materials Science
• Imaging Technology
• Physics

Background:

• Accurate imaging of submillimeter structures is crucial for material analysis.
• Existing X-ray tomography systems may lack sufficient resolution and contrast for fine details.

Purpose of the Study:

• To achieve precise structural imaging of submillimeter-sized objects.

Main Methods:

• Construction of a novel X-ray tomography system.
• Implementation of a sharp pencil beam data acquisition.
• Optimization of X-ray energy band for enhanced contrast.
• Application of deconvolution processing for projection restoration.
• Utilization of iterative revision methods for data compensation.

Main Results:
