Art and heritage are two very interesting application of terahertz techniques like imaging, spectroscopy and FMCW. Beyond the interest for the art restorers, the historians and experts of the art, the interest of this application is to be able to demonstrate and explain the possibilities of the waves terahertz on cases of studies which have sense for all the world.
Please find below articles about terahertz imaging and spectroscopy applications for art and heritage.
This paper focuses on the analysis of time-domain data regarding the measurements conducted on a French Renaissance painting realized on a metal substrate (copper). We specifically focus on the dielectric characterization of the varnish layer and its ageing consequences on THz images. Principal investigators are Quentin Cassar and Corinna Koch Dandolo. The painting The oil … Read more
In this paper, we focus on data processing applied to terahertzTerahertz radiation is electromagnetic energy commonly associated with frequencies around 0.1 to 10 THz, between microwaves and infrared, where many materials reveal distinctive propagation, absorption, and imaging behavior. More FMCW measurement of a painting. Investigated paintings FMCW radarFMCW radar transmits a continuously swept frequency and measures the beat signal produced by delayed reflections, enabling distance, thickness, and depth-resolved imaging with compact coherent hardware. More processing The proposed approach consist to use … Read more
