Terahertz technology, with superb penetration, nonionizing and femto second timeresolved features, is very suitable for nondestructive analysis and in situ detection of culture heritage objects. Research on applications of terahertz technology in the art conservation field over the past several years have been reviewed. It is summarized terahertz spectroscopy and imaging in material analysis and the detection of internal structures in objects of cultural heritage. This work reveals a broad array of applications in the field of culture heritage, providing a reference for the development of terahertz technology for the nondestructive analysis of artwork in China.
