为了验证将光学相干层析(OCT)成像技术应用于古代陶瓷无损检测，将OCT图像表现的釉面的断面特征用于古代陶瓷类别区分的可行性，利用宽波长频域OCT成像系统对选自5个窑口的8个不同釉系、色系的瓷片进行测试，得到了样品的断面结构图像，并分析了OCT图像中的气泡大小和分布、强散射颗粒分布、釉层均匀性、透射率、釉层的分层等特征。实验结果显示8个古代瓷釉样品OCT成像特征差异明显，说明OCT成像技术能基于断层图像特征对瓷釉的釉系、窑口进行区分。

In order to validate the possibility of using the optical coherence tomography (OCT) imaging technology to non-invasively exam the ancient porcelain and using the section characteristics of the glaze reflected by OCT images to ancient porcelain classification, an OCT imaging system is used to test 8 different type and color ancient porcelain chips selected from 5 different kilns. The section structure images of these samples are obtained. The characteristics of OCT images about the size and distribution of bubbles and strong scattering particles, the uniformity, stratification and transmittance of the glaze layer are analyzed. The experimental results show that the imaging characteristics of 8 different ancient porcelain samples obtained by OCT imaging technology have significant difference, illustrating that species and kilns of glaze can be distinguished based on the section characteristics by OCT imaging technology.
