摘要
同步辐射光源是一种特殊的新型光源,具有从远红外、可见光、紫外光到X射线范围内的连续光谱。鉴于高亮度、宽频谱、高偏振等优点,基于同步辐射光源的技术,尤其是X射线技术,包括X射线荧光光谱(X-ray fluorescence spectroscopy,XRF)、X射线吸收精细结构谱(X-ray absorption fine structure,XAFS)、X射线衍射谱(X-ray diffraction,XRD)和X射线断层摄影术(X-ray micro computed tomography,X-μCT)等,被广泛地应用到文物分析与保护以及考古研究等领域。主要从基于同步辐射的X射线技术在中国文物分析的角度出发,总结基于我国现有同步辐射X射线装置在相关方面的研究,并对比国外前沿研究给出展望。
Synchrotron radiation(SR)is a special novel light source with a continuous spectrum ranging from far infrared,visible,ultraviolet to X-ray regions.In view of the advantages of high brightness,broad spectra and high polarization,SR-based technologies,especially X-ray technologies[X-ray fluorescence spectroscopy(XRF),X-ray absorption fine structure(XAFS),X-ray diffraction(XRD)and X-ray micro computed tomography(X-μCT)],have been broadly applied to the analysis and conservation of cultural relics and to archeological research.This paper summarizes relevant studies in China using existing SR-based X-ray devices for the study of cultural relics,and also compares prospects with frontier foreign research.
