Jana Striová: Výzvy a pokroky v analýze malířské vrstvy (přednáška v rámci PhD Labu)

18.12., 9:00

V pátek 18. 12. od 9.00 proběhne v rámci aktivit PhD Labu AVU a ve spolupráci s ateliérem restaurování výtvarných děl malířských a polychromované plastiky přednáška Jany Striové, Ph.D. s titulem „Výzvy a pokroky v analýze malířské vrstvy: reflexní zobrazovací spektroskopie a další doplňkové nástroje“. Přednáška proběhne on-line a je otevřena všem zájemkyním a zájemcům z AVU. Máte-li zájem se zúčastnit, obraťte se prosím na martina.hrckova@avu.cz.  

Challenges and advancements in analysis of painted surface: reflectance imaging spectroscopy and other complementary tools
Jana Striova, Ph.D.
National Research Council – National Institute of Optics in collaboration with Opificio delle Pietre Dure in Florence, Italy
Recently, we have celebrated 20 years of collaboration between Opificio delle Pietre Dure and National Research Council that could be labelled as “from diffidence to synergy, and beyond…”. Nowadays, we operate in a fruitful cross-disciplinary way now defined as Heritage Science discipline.   
By way of examples, it will be demonstrated how the instrumental analysis provides support to restorers, art historians and other experts in making informed decisions related to conservation, interpretation or management of works of art. Some of these tools are available free of charge within the H2020 IPERION HS (www.iperionhs.eu) project to heritage science users, and the modalities on how to access those services will be explained.
Among the tools available, scanning reflectance imaging spectroscopy in visible-near infrared (VIS-NIR) region will be described and examples on how information on hidden features underlying the pictorial layer can be retrieved and on chemical nature of the compounds extracted. The modalities of data acquisition (single-point and line scanning) and state-of–the-art and recent advancement in data elaboration for reflectance imaging spectroscopy (RIS) will be discussed. The capability of RIS to map paint materials and visualize hidden traits beneath the surface will be demonstrated on several case studies. The fusion with complementary data, such as X-ray fluorescence (XRF) spectroscopy mapping or 3D scanning, will be addressed as well.
