Thermographic and reflectographic imaging investigations on Baroque paintings preserved at the Chigi Palace in Ariccia

In this work, two different mid-infrared imaging techniques operating in the 3-5 µm spectral range are applied to study of three paintings on canvas, dating back XVII century, preserved at Chigi Palace Ariccia (Italy). A combined approach based use pulsed thermography and reflectography is proposed for analysis ‘Primavera’ by Filippo Lauri Mario Nuzzi, ‘Ritratto di Nuzzi che dipinge un vaso fiori’ Giovanni Maria Morandi ‘Ebbrezza Noè’ Andrea Sacchi.
