Core Viewpoint - The establishment of China's first "Cultural Relics Mineral Pigment Terahertz Spectroscopy Database" in Datong fills a significant gap in the field of cultural relic protection, providing over 1,500 terahertz spectral data points for 100 types of mineral pigments, enhancing non-destructive testing capabilities for cultural heritage [1][2]. Group 1 - The terahertz wave technology is recognized as one of the "top ten technologies that will change the future world," offering unique advantages in non-destructive testing of cultural relics due to its ability to penetrate various materials without causing damage [1]. - The database includes high-quality spectral information from nine countries and regions, covering nine major color systems, and provides comprehensive data including experimental conditions and sample processing details [1]. - The release of this database supports the protection and restoration of precious cultural relics such as the Yungang Grottoes and Huayan Temple, and serves as an important reference for industry standard formulation [1]. Group 2 - Shanxi Province has applied hyperspectral technology for the first time in the digitalization project of Yungang Grottoes, achieving a comprehensive digital record from geometric shapes to material composition, marking the entry into the "spectral era" of digital protection [2].
