“…Figure 10(a) represents the 3D THz image of the complete object obtained with a volume rendering software. From the reconstruction, the internal volume of the bottle has been estimated to 650 cm 3 . With the volume rendering software, it is also possible to visualize independently the different parts of the object.…”

“…Fourier-transform infrared spectroscopy, Raman microscopy [1,2], and X-ray radiography [3] are some of the commonly used methods for the analysis of artworks. To obtain detailed information about the sample, multiple spectroscopic imaging techniques are generally utilized from X-rays, ultraviolet to infrared [4,5].…”

“…Therefore, X-ray imaging is a favoured analysis method. The application of X-rays on archaeological findings already happens by digital radiography, computed tomography [3,4], X-ray fluorescence or X-ray diffraction methods [5]. Investigating metal artefacts by X-ray imaging is a common way to get information about the material, the dimension and the preservation status of the enclosed finding.…”

Abstract:The analysis of archaeological findings reveals the remaining secrets of human history. However, it is a challenging task to investigate and simultaneously preserve the unique remains. Available non-destructive examination methods are limited and often insufficient. Thus, we considered X-ray grating interferometry as a non-destructive and advanced X-ray imaging method to retrieve more information about archaeological findings. In addition to the conventional attenuation image, the differential phase and the dark-field image are obtained. We studied the potential of the scattering-sensitive dark-field and the phase-shift sensitive differential phase image to analyse archaeological findings. Hereby, the focus lies on organic remnants. Usually, the organic materials have vanished due to decomposition processes, but the structures are often preserved by mineralisation and penetration of corrosion products. We proved that the combination of the attenuation and the dark-field image in particular, enables a separation of structural properties for fabric remnants. Furthermore, we achieved promising results for the reconstruction of sub-pixel sized fibre orientations of woven fabric remnants by employing the directional dark-field imaging method. We conclude from our results that a further application of X-ray dark-field imaging on wet organic findings and on the distinction of different types of organic remnants at archaeological findings is promising.

In recent years, research and technology made considerable progress in increasing the speed and the safety of the entire digitization process of ancient collections. Despite this, imaging ancient, fragile or un-opened documents remains a formidable challenge. We employ an alternate digitization technique for handwritten documents, exploiting x-ray tomography: Virtual X-ray Reading. Thanks to the high penetration of x-rays, we can acquire 3-dimensional (3D) tomographic images of a multi-page document without opening it. The x-ray contrast necessary for the readability is produced by the chemical composition and the consequent strong x-ray absorption of the iron gall inks -largely used for European handwritten documents. We present the development of this technology, from the chemical investigations of the inks to the tomography of an unopened Venetian testament and of an 18 th century, 200-page, handwritten book.
