Santa Maria di Collemaggio Church (L’Aquila, Italy): Historical Reconstruction by Non-Destructive Testing Techniques

Analysis of Cultural Heritage by Non-Destructive Methods: The Case of Sivas Congress Museum

“…Experts working on the conservation of cultural heritage have supported the use of non-destructive testing methods (NDT) in recent years [3], [4] because application of these techniques, structural stability and functionality are maintained without any intervention such as digging and drilling that disrupt the physical integrity [5], [6]. These techniques are used in order to identify archaeological assets buried under a heritage building [7]; determine the homogeneity, quality, or amount of deterioration of a building material [1], [8]; determine the morphology and cavities, moisture distributions, size of cracks; evaluate the injection made in the restoration of building elements [3]; observe the degree of damage to a building element damaged in an earthquake [5]; do origin analysis of archaeological artifacts [9], [10]; determine whether the gilding on the work is produced from real gold or another gold imitation material [11], [12], detect subsurface defects [13]; and investigate the compatibility of the original building material with the modern building material [14].…”

Non-destructive Investigation of Paintings on Canvas by Continuous Wave Terahertz Imaging and Flash Thermography

“…The number of publications on this subject is relatively limited, and the scope of research mostly includes mural and panel paintings (not paintings on canvas) [44,47,64]. When using the ground penetrating radar technique, interpretation of radargrams is generally non-intuitive to the novice and, in the CH field, it is usually used for thick objects, such as mural paintings [52] or historical floors [56] and not for thin objects, such as paintings on canvas, due to the operation frequency. The use of IRT can be a valid choice in order to support the THz imaging in the artwork inspection and in the distinction between genuine or fake weaving in paintings on canvas.…”

Detection of incipient defects in book bindings. A functional use of the infrared vision combined with optical and nuclear magnetic resonance (NMR) spectroscopy techniques

“…It is widely acknowledged the use of infrared thermography (IRT) method for monitoring defects in book bindings [9][10], parchment sheets [11][12] and, more recently, for the detection of hidden texts in books [13] and mural paintings [14][15]. As shown in the latest two references, the implementation of advanced techniques for processing raw thermograms enhances the results obtained [16].…”
