Scientific imaging techniques

01 - Optical imaging techniques

Optical imaging allows for the examination of surface and underlying layers of artworks without contact or sampling. CIRAM uses:

  • The raking light to reveal the reliefs, cracks, and deformations of the support,
  • Infrared reflectography to visualize preparatory drawings, pentimenti, or hidden signatures;
  • UV fluorescence to detect restorations, cleanings, or specific pigments.

These examinations are valuable for understanding the creative process, authenticating a work, or guiding a restoration. Non-destructive and deployable on-site or in the laboratory, these techniques offer conservators and experts a precise and reliable reading of pictorial or manuscript works.

02 - Radiographic imaging techniques

Radiographic techniques make it possible to explore the interior of an object without damaging it:

  • The X-ray radiograph provides a 2D image of the materials traversed, revealing cracks, restorations, additions, or heterogeneities. It is fast, portable, and ideal for on-site analyses.
  • The CT scan, performed in a laboratory, offers precise 3D modeling of complex or sealed objects, such as urns or artifacts in matrix. It allows for genuine virtual excavations.

These technologies are used alone or in conjunction with other methods such as thermoluminescence dating, and are adapted to the specific needs of art, archaeology, and conservation professionals.

CIRAM laboratories, experts in scientific imaging

For nearly 20 years, CIRAM has been putting its interdisciplinary expertise at the service of heritage professionals: museums, archaeologists, restorers, auction houses, collectors.

Our equipment – X-ray radiography, CT scan, UV fluorescence, infrared reflectography, raking light – is deployed in the laboratory or on-site, depending on the object's constraints and the project's objectives.

Each mission is conducted with absolute scientific rigor, and results in an actionable report for heritage professionals and the art market.

Are you asking yourself these questions?

Why use scientific imagery on a work of art?

It can detect restorations, identify hidden signatures, reveal preparatory drawings and analyze materials non-intrusively.

What are the advantages of scientific imaging in archaeology?

It makes it possible to study artifacts without altering them, and to carry out virtual excavations on sealed or fragile objects.

Can we carry out an on-site analysis?

Yes, our portable equipment enables us to intervene directly in museums, on archaeological sites or at a collector's home.

How long does it take to get results?

This depends on the analysis required, but we are committed to delivering results as quickly as possible.

What objects can be analyzed using scientific imaging?

Paintings, sculptures, ceramics, manuscripts, archaeological objects and historical furniture.
