ResumoIn the artwork conservation field, non contact diagnostic and imaging methods are widely used and most welcomed.In this work a new imaging tool, called Thermal Quasi-Reflectography (TQR), is proposed and demonstrated.It is based on the recording, by suitable procedures, of reflected infrared radiation in the MWIR band (3-5 μm).The technique, simple to perform, can provide very interesting results in the analysis of the painting surfaces.TQR was demonstrated in situ on two famous artworks: the Zavattari's frescos in the Chapel of Theodelinda (Italy) and the masterpiece by Piero della Francesca "The Resurrection" (Italy).
