看过纪录片《我在故宫修文物》的观众或许会对如下场景有印象:技术人员用一台仪器扫描古字画,扫描信息经过专业处理后,文物修复专家就能发现字画上肉眼看不见的信息,甚至还能分析出绘画技法和当时用的颜料。这台神奇的仪器就是中国科学院遥感与数字地球研究所研发的高光谱扫描仪。高光谱遥感为何有如此的超能力?除文物检测修复外还有哪些应用?利用高光谱技术能提取古画的颜料信息,推算颜料产地,从而能在修复时
Visitors who read the documentary “I Culture Relics in the Forbidden City” may have an impression on the following scenes: Technicians scan ancient calligraphy and painting with a single instrument, and after the information is professionally processed, experts in restoration can find the invisible information on the calligraphy and painting , Can even analyze the painting techniques and the pigments used at the time. This wonderful instrument is the hyperspectral scanner developed by Institute of Remote Sensing and Digital Earth, Chinese Academy of Sciences. Hyperspectral remote sensing why there is such a super ability? In addition to cultural relics detection and repair of what other applications? The use of hyperspectral technology can extract the ancient picture of paint information, calculate pigment origin, which can be repaired
