摘　　要：多光谱成像技术集数字成像和光谱测量技术于一体,是一种记录光学信息的新型无损分析技术。基于对国内外文化遗产领域多光谱成像技术研究现状的分析,使用自行搭建的多光谱成像系统对敦煌壁画颜料模拟试板和现代国画在300~1000 nm范围内进行光谱图像采集,检验多光谱成像系统的适用性。结果显示多光谱图像能对外观相近的不同颜料做出快速区别,结合激光显微拉曼光谱技术,可进一步识别样品中颜料的种类;同时,多光谱图像还能够揭示具有紫外激发可见荧光特性的物质分布、画稿中的底稿信息、水渍痕迹等信息。实验表明多光谱成像技术可以有效获取彩色艺术品的多样化信息,在彩色艺术品研究领域具有良好的应用前景。With digital imaging and spectral measurement, multispectral imaging technology is a new non-invasive technique to record optical information. Based on the analysis of the application of multispectral imaging in domestic and overseas cultural heritage field, simulated plate of Dunhuang mural pigments and modern Chinese paintings are analyzed using self-developed system at 300-1000 nm to prove its applicability. The results show that pigments with similar color can be identified quickly in multispectral images. Combined with laser Raman microspectroscopy, mineral phases in these pigments can be further determined. Meanwhile, the distribution of materials with ultraviolet induced visible fluorescence, the draft, the watermark in the painting can be well revealed. It is illustrated that various information of colored artworks can be obtained effectively by multispectral analysis, and the technique has good application foreground in the study of colored artworks.
