By integrating a mid-wave or long-wave infrared (MWIR/LWIR) camera, similar to those used in thermal imaging, into an interferometric setup combined with a broadband infrared source, we aim to achieve deep imaging through diffusive and/or opaquelayers such as paints, coatings, plastics, ceramics, or aged varnishes. Full-Field OCT (FF-OCT) remains largely unexplored in the mid-IR range. This project will therefore address both fundamental questions on infrared light propagation in complex scattering media and applied challenges in several fields. This internship offers an opportunity to contribute to the development of a new generation of infrared interferometric imaging tools, expanding the reach of OCT beyond its traditional spectral limits. Anticipated applications include: - Cultural heritage analysis, enabling visualization beneath painted surfaces and ceramic glazes. - Non-destructive testing, particularly for detecting subsurface defects in industrial coatings used in aerospace and advanced manufacturing.
