| 中文摘要 | A peeling off method was developed for the material discrimination technique with dual-energy, high energy X-rays (1 ~ 10 MeV) to improve the accuracy when inspected objects overlap. An alpha -curve model for material discrimination using X-rays with dual energies of 1 ~ 10 MeV was used to compare the alpha -curves before and after the overlap to reconstruct the alpha -curves of the overlapped objects. Tests were made on a full-scale prototype with X-ray boundary energies of 9 MeV and 6 MeV to discriminate overlapped objects and to calculate the discrimination accuracy. The results show that the method can be used to accurately identify the overlapped objects. |
