“…The first internationally available reports on the use of the OCT technique for artwork analysis are from 2004 by Yang et al [13], Targowski et al [41], and Liang et al [30]. In these early papers, the major fields of interest were already recognised: examination of varnish and glaze layers of paintings and semi-transparent solids such as jades and glazed ceramics.…”

“…Since the picture is intended to be viewed though the glass, the paint layers decisive for the visual effect are directly adjacent to the glass support. This renders them inaccessible to physical inspection, and the advantage of using OCT for this task, developed by Iwanicka et al [8,41], is irrefutable. Apart from mere detection of various stages of formation of blisters between the glass and the paint layer, the results of filling them with consolidation adhesives during previous conservation treatment were also evaluated.…”

“…7). A similar application of OCT is the examination of a painted photograph, part of a collage, glued face-down to a sheet of glass [41]. However, in this case, for technological reasons, both the glass and the glue layer had been damaged.…”

“…Another group of objects examined with OCT from the very beginning are those made of porcelain and faience [17,37,41]. The most comprehensive study was made by Yang et al [16], examining various items of 10th-14th century Chinese glazed ceramic shards.…”

Optical Coherence Tomography: its role in the non-invasive structural examination and conservation of cultural heritage objects—a review

A brief introduction to Optical Coherence Tomography (OCT) is presented, stressing the origin of the tomographic signal and the detection methods defining various modalities of the technique. The parameters of the tomographs, such as axial and lateral resolution, wavelength and intensity of the probing light, imaging range, time of examination, and sensitivity are then defined, and a paradigm for interpreting the OCT tomograms provided. The second part of the article comprises a review of the utilisation of OCT for structural examination of artworks, illustrated with some representative results. Applications to the structural imaging of semi-transparent subsurface layers such as varnishes and glazes, of underdrawings and of reverse painting on glass, are described first, and then applications in the examination of the structure and state of preservation of historic glass, jade, glazed porcelain and faience are discussed. Finally, the use of OCT combined with LIBS analysis and laser ablation of surface layers is presented.
