摘　　要：针对主观颜色分析受照明光源、观察者等因素影响的问题,本文采用可见光谱识别不同朝代典型壁画的颜料信息,然后根据色度学理论,客观地分析了古代壁画的颜色特征和历史流变。本文搭建了非接触式获取系统,并采用该系统对莫高窟不同朝代典型洞窟壁画的可见光谱数据进行了无损采集。此外,本文模拟古代工艺制备颜料样本,测量其可见光谱和粒径尺度数据,建立颜料标准数据库。分析颜料的可见光谱与其物质成分、粒径及颜色特性之间的关联,并据此构建基于可见光谱的壁画颜料的识别方法,识别莫高窟典型洞窟壁画的颜料信息。本文通过将识别的颜料信息与颜料标准数据库数据进行对比,客观地分析了莫高窟壁画的颜色特征和历史流变。Subjective color analysis is affected by factors such as lighting sources and observers.To avoid this subjectivity,the pigments of ancient murals are identified using visible spectroscopy,and the characteristics and historical evolution of the ancient murals'color are then analyzed objectively using the chromatic theory.We built a nondestructive acquisition system and used it to capture the visible spectra of the typical Mogao Grottoes murals painted in different dynasties.Many typical pigment samples were prepared by simulating the ancient process.The visible spectra and particle sizes were measured to construct a standard reference database from the obtained results.After analyzing the relationships among the visible spectra,material composition,particle size,and color attributes,a pigment identification method was proposed to identify the pigment used on the murals.The color attributes and historical evolution of the Mogao Grottoes murals were analyzed by comparing the identified pigments with those in the reference database.
