Crystal-based X-ray interferometry (CXI) detects phase shifts by using the superposition of waves, and its sensitivity is highest among other phase-detecting methods. Therefore, phase-contrast imaging (PCXI) CXI has density resolution PCXI methods enables fine, non-destructive observation with a below sub-mg/cm3. It thus been applied in wide range fields, including biology, medicine, geology, i...

Todays, X-ray imaging system for cargo and containers inspecting of country gates are highly regarded. The dual energy imaging system due to the use of two beams with different spectrums can extracts more information about the materials in cargo than the conventional X-ray imaging system. Since the X-ray beam is an ionizing radiation, three parameters should be taken into account including just...
