    2. Optical coherence tomography and non-linear microscopy for paintings – a study of the complementary capabilities and laser degradation effects

      Optical coherence tomography and non-linear microscopy for paintings – a study of the complementary capabilities and laser degradation effects
      his paper examines for the first time the potential complementary imaging capabilities of Optical coherence tomography (OCT) and non-linear microscopy (NLM) for multi-modal 3D examination of paintings following the successful application of OCT to the in situ, non-invasive examination of varnish and paint stratigraphy of historic paintings and the promising initial studies of NLM of varnish samples. OCT provides image contrast through the optical scattering and absorption properties of materials ...

    4. A holistic multimodal approach to the non-invasive analysis of watercolour painting

      A holistic multimodal approach to the non-invasive analysis of watercolour painting
      the materials (pigments, drawing materials and paper) and painting techniques of watercolour paintings is presented. The non-invasive imaging and spectroscopic techniques include VISNIR reflectance spectroscopy and multispectral imaging, micro-Raman spectroscopy, X-ray fluorescence spectroscopy (XRF) and optical coherence tomography (OCT). The three spectroscopic techniques complement each other in pigment identification. Multispectral imaging (near-infrared bands), OCT and micro-Raman complement each other in the visualisation and identification of the drawing material. OCT probes ...

    5. High resolution Fourier domain Optical Coherence Tomography at 2 microns for painted objects

      High resolution Fourier domain Optical Coherence Tomography at 2 microns for painted objects
      Optical Coherence Tomography has been successfully applied to the non-invasive imaging of subsurface microstructure of a variety of materials from biological tissues to painted objects of art. One of the limitations of the technique is the low depth of penetration due to the strong scattering and absorption in the material. Previous studies found that for paint materials, the optimum window for large depth of penetration is around 2.2 microns ...

    6. Ultra-high resolution Fourier domain optical coherence tomography for old master paintings

      Ultra-high resolution Fourier domain optical coherence tomography for old master paintings
      In the last 10 years, Optical Coherence Tomography (OCT) has been successfully applied to art conservation, history and archaeology. OCT has the potential to become a routine non-invasive tool in museums allowing cross-section imaging anywhere on an intact object where there are no other methods of obtaining subsurface information. While current commercial OCTs have shown potential in this field, they are still limited in depth resolution ( 4 m in paint ...

    7. Optical coherence tomography in the 2um wavelength regime for paint and other high opacity materials

      Optical coherence tomography in the 2um wavelength regime for paint and other high opacity materials
      An optical coherence tomography system using a compact fiber source emitting amplified spontaneous emission at central wavelength of 1960 nm with bandwidth of 40 nm is developed to enhance the probing depth in a highly scattering material with low water content. Examples of application to paint are used to demonstrate significantly improved penetration depth in high opacity materials in the 2-m wavelength regime.

    8. Long wavelength optical coherence tomography for imaging of painted objects

      Long wavelength optical coherence tomography for imaging of painted objects
      Optical Coherence Tomography has been successfully applied to the imaging of painted objects in recent years. However, a significant limitation is the low penetration depth of OCT in paint because of the high opacity of paint due to either scattering or absorption. It has been shown that the optimum spectral window for OCT imaging of paint layers is around 2.2m in wavelength. In this paper, we demonstrate a 1950nm ...

    10. Optimum spectral window for imaging of art with optical coherence tomography

      Optimum spectral window for imaging of art with optical coherence tomography
      Optical coherence tomography (OCT) has been shown to have potential for important applications in the field of art conservation and archaeology due to its ability to image subsurface microstructures non-invasively. However, its depth of penetration in painted objects is limited due to the strong scattering properties of artists paints. VISNIR (4002,400 nm) reflectance spectra of a wide variety of paints made with historic artists pigments have been measured. The ...

    1. By using a suite of complementary, non-invasive technologies we're able to uncover just as much information from historic paintings than traditional destructive techniques. This helps to deepen our understanding of art history as it allows us to correlate the material actually found on the paintings with historical records.

    2. It was first developed to look at 3D in vivo imaging of the eye..In 2004, we started using it for paintings, but it's the first time that we're using it to scan a wall painting....You can see the structure of the layers of paint and varnish...The technique allows you to measure the thickness of each layer non-invasively.
