| Abstract | 本文利用高光譜技術分析了兩幅模擬壁畫,通過比較模擬壁畫顏料與標準顏料光譜曲線的形狀特征及其一階導數特征峰和計算顏料光譜匹配度,有效準確地甄別出藍銅礦、孔雀石、雌黃、藤黃、雄黃、鉛丹和朱砂,但無法判別胭脂。同時,高光譜技術鑒定出的西藏拉薩大昭寺轉經廊壁畫中藍銅礦、孔雀石、鉛丹和朱砂顏料,與便攜式X射線熒光元素成分結果一致。本研究結果表明高光譜技術可無損與準確地鑒定中國古代顏料,與便攜式X射線熒光元素成分分析相結合,是壁畫現場無損快速分析的重要手段。
Two simulated wall paintings were analyzed with hyperspectral technology and their spectral information collected. Comparing their reflectance spectral curves, characteristic reflectance peaks, first derivative peaks and spectral similarity shared with wall paintings of standard pigments, we have effectively and accurately differentiated azurite, malachite, orpiment, realgar, gamboge, red lead, and cinnabar, though kermes could not be identified. In addition, the identification of pigments such as azurite, malachite, red lead, and cinnabar in the wall paintings at Jokhang Monastery in Lhasa, Tibet, can be verified by portable XRF analysis. This research indicates that hyperspectral technology combined with portable XRF is an effective method for non-destructive and large-scale in-situ investigation of mural pigments. |
