Abstract We present an opto-thermal approach based on the use of active infrared thermography (IRT) for the study of texts hidden inside the bookbinding structure of ancient books. In particular we focus our investigation on the detection and characterization of texts on paper scraps, belonging to earlier handwritten or printed leaves, used for the making of bookbindings and lying between the end papers and the cover. A qualitative description of the physical mechanisms allowing the identification of texts is proposed and a comparative analysis of the results obtained by means of different IRT experimental configurations is presented. The results show that active IRT can be a very useful tool for the detection and the identification of underlying texts whose reading can provide useful information on the specific history of ancient books. Zusammenfassung Die Anwendung von aktiver Infrarotthermographie (IRT) zur Erfassung von Texten, die in Einbandstrukturen verborgen sind, wird vorgestellt. Insbesondere wurden Texte auf Fragmenten, die fur die Buchdeckenherstellung verwendet wurden, beziehungsweise sich zwischen Vorsatz und Buchdeckel befinden. Eine Beschreibung der physikalischen Grundlagen fur die Texterfassung mit IRT wird gegeben ebenso wie die Prasentation ausgewahlter Untersuchungen an historischen Objekten. Die prasentierten Resultate zeigen, dass aktive Infrarotthermographie eine geeignete Methode fur die Erfassung von verdeckten Textfragmenten darstellt und wichtige Informationen zur Geschichte historischer Bucher beziehungsweise Bucheinbande liefern kann. Résumé Nous présentons une approche qui se base sur l’utilisation active de la thermographie infrarouge (IRT) pour l’étude de textes cachés à l’intérieur de la structure reliée des livres anciens. L’examen s’est centre surtout sur la détection et la caractérisation de textes sur les fragments de papier provenant de feuilles écrites auparavant à la main ou imprimées et qui ont servi dans la fabrication des reliures et qui se trouvent entre les dernières feuilles de garde et la couverture des livres. On présentera une description des mécanismes physiques permettant l’identification des textes et une analyse comparative des résultats obtenus au moyen de différentes configurations expérimentales d’IRT. Les résultats présentés démontrent que La thermographie infrarouge active s’avère être un outil très utile dans la détection et la caractérisation de textes sous-jacents dont la lecture peut fournir de précieuses informations sur l’histoire spécifique de livres anciens.

Thermographic analysis of bronze sculptures

In this work we investigate various aspects of the finishing process in ancient bronze sculptures by means of active infrared thermography (IRT). Active IRT provides information on surface and sub-surface features of the investigated artefact, by analysing the heat diffusion process induced within the sample by appropriate thermal stimulations usually produced by absorption of light emitted by different sources. The aim of this research is, in particular, to investigate the processing of bronze surfaces, revealing repairs like plugs, fillings, local castings and concealed marks.

Abstract In this work, active infrared thermography was applied to study a seventeenth-century painting on paper, namely the Chigis family tree, housed at Palazzo Chigi in Ariccia (Rome). Thermography was performed before and after restoration to obtain information used in planning the restoration and also to assess its effectiveness. Infrared thermography provided important information on the artifact structure, areas of damage, structural defects, and the state of adhesion between different layers of the composite artifact before and after the treatment.
