Abstract
Chemometric analysis was applied on terahertz absorbance 3D images, in transmission. The goal is to automatically discriminate some explosives on images and quantify mixtures of RDX/PETN in the frequency range of 0.2–3 THz. Partial Least Square (PLS) was applied on THz absorbance multispectral images to quantify individual product inside pure samples and mixtures at each pixel on the image. Then the best score obtained is used to display the samples' images and provide the optimal frequencies combination for recognition purpose.
