X-ray micro computed tomography-aided calibration of laser-induced breakdown spectroscopy depth profiling for archaeological ceramics examination

Original language description

The investigation of archaeological samples, such as ancient ceramics, provides more details about the past. In this work, we suggest a new approach for the calibration of a depth profiling of ceramic fragments with glazed layers. X-ray Micro Computed Tomography (μCT) serves as a calibration method for a depth-profile analysis using Laser-Induced Breakdown Spectroscopy (LIBS). In this case, μCT benefits from different contrasts of the glaze layer (containing lead) and the ceramic matrix (lead-free). Non-destructive μCT scans provide a dimensional analysis and a 3D observation of LIBS craters with a resolution at the micrometer level. The LIBS analysis combined with μCT enables a precise depth-wise calibration to the number of laser pulses. Moreover, a visualization of the ablation process allows observing the laser beam as it passes through the glaze, the interface and the ceramic matrix. The ablation rate determined using μCT scans enabled the differentiation of individual phases of the ablation process penetrating the surface layer. As each of these steps is characterized by a different ablation rate, a more precise calibration for the depth calculation is possible. Such an approach is unique and may be further used in a depth profile calibration regardless of the analyzed sample.
