中文摘要	多光谱成像技术集数字成像技术和光谱测量技术于一体，是一种新型的无损分析技术，具有成像范围广、光谱分辨率高等特点。近年来，多光谱成像技术被用于油画、书稿等文物信息的记录和研究，利用光谱图像获取文物样品的颜色信息、物相组成、病害特征、历史痕迹等多层次信息。凭借快速高效、便携灵活、信息直观全面等优势，多光谱成像在文物研究和保护领域倍受重视和关注。本论文主要探索多光谱成像在更多文物研究中的潜力应用，优化多光谱成像实验技术，探讨如何更好地结合其他已有的无损分析技术，使多光谱成像技术更好地服务于文物研究和保护。 本研究的主要工作内容包括以下5个方面： （1）基于对国内外文化遗产领域内多光谱成像技术应用现状的分析，对比出现的多光谱成像设计和商业设备，结合科研需求自行搭建多光谱成像系统，成像范围覆盖近紫外至近红外。 （2）使用自行搭建的多光谱成像系统对壁画颜料层模拟试板、国画等现代彩色艺术品进行光谱图像采集，比对分析不同波段的光谱图像和不同拍摄模式下获取的光谱图像，探索多光谱成像在研究壁画、国画两类文物方面的适用性。结合激光拉曼光谱技术，识别现代彩色艺术品中所用的颜料。并将多光谱成像与高光谱成像进行对比分析。 （3）采用多光谱成像系统对安徽南陵宋墓出土送葬幡上消失的字迹进行重现研究。 （4）采用多光谱成像系统结合傅里叶红外光谱技术对四川大学博物馆馆藏6幅清代唐卡进行无损分析，获取的有关唐卡的丰富信息为研究唐卡的材料构成、保存状态评估、制作工艺、绘画内容和技法等方面提供了科学依据，也展示了多光谱成像技术在绘画类艺术品研究领域的广阔应用前景。 （5）将多光谱成像与激光拉曼光谱、X射线荧光光谱、X射线衍射等点分析技术结合，对5件战国时期多色人造硅酸盐制品表面物质的光谱特性、化学成分和物相结构进行了无损分析。探讨了常见的分析技术在文物分析中的特点和局限，为提高文物分析效率和降低文物受损风险，对古代硅酸盐制品的分析技术组合和研究方法进行了探索。
英文摘要	Multispectral imaging technology, which records simultaneously digital spatial and spectral information, is a new non-invasive analytical technique, characterized wide response range of imaging and high spectral resolution. Recently multispectral imaging technology is applied to the record and research information of cultural objects, like paintings and manuscripts. Multi-level information of cultural objects, like color, material composition, deteriorations feature, historic trace and so on, can be obtained through spectral images. Multispectral imaging has gained importance and attention in the field of art conservation and research, due to the advantage of high efficiency, good flexibility that convenient to use on site, getting visual and rich information. In the research, explore the potential application in more cultural objects, optimize the experimental technique, and discuss how to combine with other noninvasive analytical techniques effectively, to make multispectral imaging technology to be applied for art conservation and research better. The main 5 contents of this research are listed as follows: (1) Based on the analysis of the application of multispectral imaging in domestic and overseas cultural heritage field，compared with existing multispectral imaging designs and commercial device, a multispectral imaging system is developed ourselves for the demand of research, achieving a near ultraviolet to near infrared range sensitivity. (2) Spectral images of modern colored artworks, simulated plate of mural pigments and Chinese paintings, have been obtained by self-developed system. The applicability of multispectral imaging in the research of mural and Chinese paintings is explored through comparative analysis of spectral images in different band or different mode. Pigments in the modern colored artworks are identified by laser Raman spectrometer. Comparative analysis of multispectral imaging and hyperspectral imaging has been done. (3) Multispectral imaging system is applied to the study of the funeral streamer for reconstruction of scripts. The funeral streamer was unearthed from Nanling county in Anhui Province and dated from Han Dynasty. (4) Multispectral imaging system with Fourier transform infrared spectrometer is applied to implement noninvasive analysis of 6 Thangkas from Sichuan University museum. Data obtained provide scientific basis to identify material, conservation state, workmanship, drawing content and skill and so on about Thankas. It is illustrated that multispectral analysis has good application perspective in the study of painting art. (5) The spectral properties, chemical compositions and phases of materials constituting the surface of 5 ancient polychromatic silicate artifacts have been analyzed non-invasively by self-developed multispectral imaging system, X-ray fluorescence spectrometer and laser Raman spectrometer. The feature and limitation of commonly used analytical techniques are presented. Technical combination and research method for ancient silicate artifacts are explored in order to increase efficiency of analysis and reduce the risk.
