Applicability of Optical Coherence Tomography at 1.55 μm to the Examination of Oil Paintings

Spatially Resolved Stress Measurements in Materials With Polarisation-Sensitive Optical Coherence Tomography: Image Acquisition and Processing Aspects

“…with index‐matching gel on the sample surface) or by numerically correcting the images, as demonstrated, e.g. with a ray‐tracing procedure by Szkulmowska et al [11]. As regards the current depicted reflectivity images in Figure 2, no specific features like microparticles are visible in the interior, and the speckle pattern shows no correlation between the unloaded and loaded state, ruling out in this case strain determination by correlation techniques like OCT elastography [12].…”

From medical to art diagnostics OCT: a novel tool for varnish ablation control

“…The main drawback of the OCT technique is usually high absorption of the light by paint layers, especially in the visible range. In the infrared, the light of wavelengths of 0.82 µm, 3 1.3 µm, 4 and 1.5 µm 3 have already been used with some success: if pigments absorbed the light moderately, the cross-section of the paint layer was visible. However, the majority of pigments are not transparent enough and this application does not seems to be very promising for common practice.…”
