About this Research Topic
A major challenge in heritage science is the non-invasive cross-sectional analysis of painted artworks. Measuring the micrometric thickness of surface paint layers is essential to assess their compactness and adhesion in order to evaluate the object's state of conservation. In-depth analysis is also useful in the context of a restoration process, such as the cleaning, to monitor the removal of deposit materials or selective thinning of protective coatings and patinas. Low-energy radiation probes are generally used in a non-invasive approach.
The presence of opaque media can significantly hinder the penetration of the incident radiation and signal collection from within the materials being examined. At present, there is no technique that can uniquely and non-invasively measure the thickness of heterogeneous and optically opaque materials such as pictorial layers.
The scope of this Research Topic is to update the state of the art of methodologies for the non-invasive stratigraphic analysis of painted artworks. Specifically, it will focus on the application of multi-analytical approaches and cutting-edge data processing methods for stratigraphic visualization and thickness measurements, as well as the analysis of the internal composition (chemical distribution). Particularly suited to this topic are studies involving the application of established and/or newly introduced methods in the field of cultural heritage such as:
- Optical Coherence Tomography (OCT)
- Photoacoustic techniques
- Nonlinear optical microscopies
- Terahertz imaging
- Confocal microscopies
Papers focused on these specific technologies and their further developments are particularly welcome to this article collection.
