Point-projection backlighting radiography technology based on micro-spot X-ray source generated by short-pulse laser provides high-spatial high-temporal resolution images of objects, and has been widely used in ICF physics experiments, high energy density physics and other fields. Based on the picosecond and femtosecond lasers of the XG-III laser facility, we have developed a laser-driven dual-axis X-ray radiography platform. This new platform is designed to record two orthogonal X-ray radiographs with a large field view (~5 mm) and high spatial resolution (≤20 μm). Two X-ray sources was generated using two orthogonal micro-wires irradiated by the short pulse lasers. The dual-axis radiographs of material dynamic fragmentation process were obtained, providing abundant image data for physical research.
