光学相干断层扫描（OCT）是一种非侵入性、非破坏性的技术，对于艺术作品的研究非常有趣。我们的设备基于迈克尔逊干涉仪，适用于记录可见光范围内的信息。该系统允许以微米分辨率对绘画进行三维成像。呈现图案层的 3D 成像，其中嵌入粘合剂中的颜料清晰可见。此外，经过调整的信号处理可以访问颜料发出的光谱信息。对粉末中颜料的测试表明它们的光谱响应是不同的。
Optical Coherence Tomography (OCT) is a non-invasive and non-destructive technique which is very interesting for the study of works of art. Based on a Michelson interferometer, our device has been adapted for the recording of information in the visible range. This system allows three-dimensional imaging of painting with a micrometer resolution. 3D imaging of pictorial layers is presented where the pigments embedded in the binder are clearly visible. Furthermore, an adapted signal processing gives access to the spectral information issued from pigments. Tests on pigments in powder are presented and show that their spectral responses are different.
