Abstract
Cultural relics are a symbol of various times. The protection and restoration of cultural relics is a multidisciplinary work covering archaeology, physics, chemistry, and biology, etc. Exploring scientific means of nondestructive testing has always been the development direction of cultural relic protection workers. Terahertz has been widely used in various fields as an emerging discipline in the past 20 years. Utilizing the terahertz technology to the cultural relic has also been a research hotspot in recent years. This paper mainly describes the application of terahertz reflection imaging to a lacquer box. The experimental results show that the lacquer box sample has a double-layer structure. The bottom layer is a wooden basis, however, the upper surface is painted with lacquer and painted on it in order to achieve the purpose of decoration. The results demonstrate that the potential of terahertz reflection imaging can carry out non-destructive testing of samples with layer structure to study whether there is damage inside.
