Abstract:
Terahertz (THz) radiation enables non-destructive, depth-resolved analysis of layered artworks. This study demonstrates THz multispectral imaging's ability to reveal concealed text beneath mock-up of pictorial layers, reconstructing hidden narratives at varying depths through frequency-domain analysis. Simultaneously, it maps pigment composition, providing valuable chemical information. Showcasing the power to penetrate and decipher stratified materials, this work establishes THz multispectral imaging as a crucial tool for unlocking hidden secrets and characterizing materials in Cultural Heritage artifacts.

Transmittance is defined as the ratio of the radiant power passing through a sample to that from the radiation's source. Multiplying the transmittance by 100 gives the percent transmittance (%T), which varies between 100% (no absorption) and 0%...
