Illuminating the Past: Photonics for Cultural Heritage Preservation and Discovery

Photonics for Cultural Heritage

Advancements in technology have revolutionized the study and preservation of cultural heritage, enabling more effective conservation strategies. One of the greatest challenges is achieving real-time, non-invasive, and stratigraphic monitoring of cleaning treatments – moving beyond subjective assessments. Optical technologies provide groundbreaking solutions, including multi-spectral imaging and Optical Coherence Tomography (OCT). Among them, OCT (an interferometric techniques that enables obtaining micrometer-level depth resolution) stands out for its precision in revealing subsurface details, though its effectiveness can be limited when analyzing highly opaque layers.

Our research in the field:

  • Supporting conservators with photonics: developing innovative approaches that combine OCT with complementary techniques, particularly fluorescence imaging, to provide conservators with quantifiable data on material removal. This integration ensures safer, more precise, and effective restoration, reducing subjectivity.

Key technologies & expertise areas:

  • Photonics: design and development of innovative fiber-based devices.
  • Artificial Intelligence: data analysis & predictive modeling.

Bridging Art and Science: a thesis in photonics for cultural heritage conservation allows you to pioneer non-invasive techniques that unveil hidden details, safeguard priceless artifacts, and revolutionize restoration – where cutting-edge technology meets history.

Possible activities and roles within:

Preserving the past with photonics

    • Innovation in Cultural Heritage Conservation: develop a real-time, non-invasive technique to precisely measure the thickness of protective transparent layers (e.g., Paraloid® B72) on ancient artifacts, such as Egyptian blue-covered surfaces, ensuring safer and more effective restoration. Leverage the synergy of OCT and fluorescence imaging to reveal hidden structural details without damaging precious artworks.
    • AI Driven Restoration: design and validate cutting-edge AI algorithms for OCT image segmentation, enabling precise layer identification and automated measurement of thickness and roughness.

Innovate at the intersection of technology and history, unlocking new possibilities for the preservation of cultural treasures worldwide in cooperation with one of the most prestigious conservation centers.
