It offers a micrometer-level in-depth resolution and, therefore, is well suited for the investigation of fine sub-surface details of structures that absorb infrared light moderately, such as varnishes, glazes, and underdrawings of paintings on canvas, reverse painting on glass, glazes on porcelain and faience, jade, historical glass, and many others. Images obtained by OCT (the tomograms) are usually presented conveniently as cross-sectional views, similar to microscopic photographs of cross-sections of samples collected from the object.<br \/>\nA brief introduction to the technique and essentials of the construction of the OCT instruments will be presented, and an overview of commercially available instruments will also be given. The advantages and limitations of the technique will be addressed, and a key to reading tomograms will be provided. Then, using examples from our practice, it will be shown how the OCT technique may be used to examine the structure of various artworks, trace former conservation attempts, and help monitor some restoration procedures.<\/p>\n<p style=\"text-align: justify;\"><!--more--><\/p>\n<p><strong>You will learn<\/strong><\/p>\n<ul>\n<li>How to read the OCT tomograms<\/li>\n<li>Which structures can and which cannot be examined with OCT<\/li>\n<li>What heritage objects can be examined with OCT<\/li>\n<li>How OCT can be useful for the restoration of artworks<\/li>\n<li>How to choose the commercial system best suited to your needs<\/li>\n<\/ul>\n<p><strong>Key topics we\u2019ll cover<\/strong><\/p>\n<ul>\n<li>OCT concept<\/li>\n<li>Performance and parameters of the OCT instruments<\/li>\n<li>Application of OCT to examination of the structure of artworks<\/li>\n<li>Utilisation of OCT in the restoration practice<\/li>\n<\/ul>\n<p><strong>Wi\u0119cej informacji oraz rejestracja:<\/strong><\/p>\n<p><a href=\"https:\/\/www.iperionhs.eu\/lecture-1-2nd-edition-2023-24\/\">https:\/\/www.iperionhs.eu\/lecture-1-2nd-edition-2023-24\/<\/a><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Pierwszy w drugim roku\u00a0\u00a0publiczny wyk\u0142ad (w j\u0119zyku angielskim) organizowany przez europejskie projekty IPERION HS\u00a0i ERIHS IP tym razem po\u015bwi\u0119cony b\u0119dzie\u00a0Optycznej Koherencyjnej Tomografi w zastosowaniu\u00a0do badania obiekt\u00f3w\u00a0zabytkowych.
