    1. Application of graphically oriented programming to imaging of structure deterioration of historic glass by optical coherence tomography

      Application of graphically oriented programming to imaging of structure deterioration of historic glass by optical coherence tomography
      Optical Coherence Tomography (OCT) is an interferometric method utilising light of low temporal coherence for noninvasive structural imaging of objects weakly absorbing and scattering light. In this contribution, using various examples of images of objects made of glass affected by the atmospheric corrosion and/or by crizzling, we demonstrate a software developed in our laboratory specifically for 3D OCT imaging of samples with a fine structure. For this task we employed the OpenGL platform (Open Graphics Library), an Application Programming Interface (API) for writing applications dedicated to interactive 3D computer graphics. In our application we have utilized texture rendering with ...

    2. Optical Coherence Tomography for Non-Destructive Investigations of Structure of Objects of Art

      Optical Coherence Tomography for Non-Destructive Investigations of Structure of Objects of Art
      In this contribution the Optical Coherence Tomography (OCT), as a novel tool for non-invasive structural imaging of selected objects of cultural heritage, will be reviewed. This technique relies on multispectral interference o f infrared light and therefore is well suited for investigation of transparent and semi-transparent structures. The technique originates from medical imaging and has been present in conservation science since 2004. Until now it has been successfully utilized in imaging of varnishes, glazes and underdrawings of paintings, glazes on porcelain and faience, structure of archaic jades, stained and archeological glass, parchment and recently for revealing the surface details of ...
