Application of Terahertz Time-of-Flight Imaging to Lacquer Box
摘要
对文物的保护和修复是一项覆盖考古、物理、化学及生物等多学科交叉的工作,利用各种科技手段无损地表达文物的历史意义一直是文保工作者的发展方向。太赫兹作为近二十多年来的新兴学科,被广泛应用于各个领域,例如安检、药品质量监督和半导体等,尝试将太赫兹应用到文保领域也是近年来的研究热点。主要讲述太赫兹飞行时间成像在漆器盒子样品上的应用。实验结果表明,研究的漆器盒子样品具有至少两层结构,胎体是木质材料,在木质材料的表面涂漆并在上面描绘不同的图案,达到装饰的目的。并且可以通过太赫兹飞行时间成像检测漆盒中的胎体也就是木质结构内部是否存在损坏。
Abstract
Protection and restoration of cultural relics are applicable to various disciplines such as archaeology, physics, chemistry, and biology. Conservators have always been interested in exploring a nondestructive test. Among these in situ analysis, terahertz technology has widely applied to various areas as an emerging subject in the past 20 years, including security check, drug quality supervision, semiconductors and so on. Recently, the application of terahertz imaging in the field of cultural security has become a popular topic. In this paper, a lacquer box is investigated through terahertz time-of-flight imaging. Experimental results demonstrate that the lacquer box has a bilayer structure. The completed wood material is considered to be the carcass, the surface of which is painted with different decorative patterns. In addition, terahertz time-of-flight imaging can be used to detect damage inside the carcass, i.e., the wood structure in the painted box.
