Evaluation of art subjects implemented in the marquetry technique by the optical coherence microscopy method

Evaluation of internal microstructure of decorative and applied art objects implemented in the intarsia and marquetry techniques by the optical coherence tomography method is considered. The high resolving optical coherence microscope with a radiation source with tunable wavelength in the range of 1305 ± 75 nm was applied. The ability to analyse layered microstructure of wood object surface layer in intarsia regions is demonstrated. The geometric features evaluation of the object's microstructure in the areas of interest was conducted. Systematisation of layers structure and typical defects inherent in intarsia regions was performed considering the structural features that may be important for restoration of such objects. Examples of experimentally obtained B‐scans and three‐dimensional representations of sample fragments of microstructure studied by the optical coherence microscopy method are given.
