摘　　要：采用光学相干层析(OCT)成像技术对河南和安徽出土的新石器时代至宋代的几种陶瓷质文物(彩陶、漆绘陶、唐三彩、绞胎釉陶、青瓷和钧瓷)的断面结构进行无损分析,获取了不同类别陶瓷器的表层(颜料层、底漆层和釉层)、中间层、胎釉结合面以及胎体表面的断面结构图像特征。通过这些结构图像,探讨了不同陶瓷器的制作工艺特点,同时也讨论了OCT成像技术分析不同类别陶瓷文物的断面结构的优点和局限。Utilizing the optical coherence tomography （OCT） imaging technology, we nondestructively analyzed the section structure of some ceramic cultural relics （such as colored pottery, lacquer painted pottery, tri-colored glazed pottery of the Tang Dynasty, glazed pottery with twisted body, celadon and Jun porcelain） unearthed from Henan and Anhui provinces and dated from Neolithic Period to the Western Han Dynasty. We obtained the section structure imaging characteristics of the surface （the layers of pigment, lacquer and glaze）, the middle layer, the glaze/body boundaries and the body of the different type ceramic objects. The production process characteristics of the different ceramic antiquities were discussed based on the characteristics. In addition, we also discussed the advantages and limitations of the OCT imaging technology in analyzing the section structure of diverse ceramic culture relics.
