Terahertz (THz) spectroscopy and imaging techniques have been applied to investigate cultural heritage objects. In particular, time domain THz imaging using a THz pulse as a probe makes it possible to observe cross-sectional images and/or sliced images of artworks. The information about the internal structure of artworks is useful for conservation planning. This chapter introduces heritage science and the advantages of using the THz frequency region with several case studies.
