Terahertz for art restorers

Terahertz time domain imaging, FMCW and spectroscopy are useful tools for art restorer to inspect paintings and other cultural. Thanks to the different terahertz equipments present on the terahertz platform in Bordeaux, we have set up collaborations with art restorers and researchers working on the analysis of works of art with terahertz. This article presents different results obtained with our systems.
