Terahertz frequency modulated continuous wave imaging advanced data processing for art painting analysis

In this paper, we focus on data processing applied to terahertz FMCW measurement of a painting. Investigated paintings FMCW radar processing The proposed approach consist to use longitudinal information of FMCW signal to adjust amplitude. This calibration process was tested on a stepped target and then on the investigated painting, giving a more homogeneous result,…

Terahertz Spectroscopy and Quantum Mechanical Simulations of Crystalline Copper-Containing Historical Pigments

Terahertz spectroscopy is a non-destructive analytical technique used in art conservation and restoration. It can provide compelling data concerning the composition and condition of culturally valuable and historical objects. Terahertz spectral databases of modern and ancient artists’ pigments exist, but lack explanations for the origins of the unique spectral features. This paper present terahertz spectra…

Art Painting Diagnostic Before Restoration with Terahertz and Millimeter Waves

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…
