Abstract

: Technical digital imaging is a non-destructive and contactless technique that is increasingly used to study wall paintings. The methodology is based on the images acquisition in different wavelengths domains. A painted lintel in the tomb of King Takelot I ( 22 nd dynasty, 887-873 BC ), at the archa eo logical site of Tanis (Egypt), which shows a fragile surface, has been investigated in this way. Images under direct light, raking light, favouring near IR radiation, catching the fluorescence response under UV have been made. Ortho -photographs and generated depth maps at both macro- and micro-scales using a digital camera and contactless e-microscope have also been performed. The images revealed the presence of Egyptian blue, red ochre, carbon black. They also have provided additional information on the degradation patterns and the nature of soluble salts that are chloride and sulphate based compounds, the main origin of the degradations and helped to detect the traces of past restoration.

壁画研究的技术成像输入:门楣的例子(埃及沙克耶塔尼桑埃尔哈加尔国王塔克洛特一世墓)
技术数字成像是一种非破坏性和非接触式的技术,越来越多地用于研究壁画。该方法是基于不同波长域的图像采集。在塔尼斯(埃及)的考古遗址上,国王塔克洛特一世(第22王朝,公元前887-873年)墓中的一个彩绘门楣,显示出一个脆弱的表面,已经用这种方法进行了调查。在直射光下、倾斜光下、近红外辐射下、紫外下捕捉荧光响应下的图像。还使用数码相机和非接触式电子显微镜在宏观和微观尺度上进行了正射影和生成深度图。图像显示了埃及蓝,红赭石,炭黑的存在。它们还提供了关于降解模式和可溶性盐(氯化物和硫酸盐基化合物,降解的主要来源)性质的额外信息,并有助于探测过去恢复的痕迹。
