近年来，光学相干层析成像技术已成功地应用于彩色物体的成像。然而，一个显著的限制是OCT在涂料中的低穿透深度，因为涂料由于散射或吸收而具有高不透明度。研究表明，油漆层OCT成像的最佳光谱窗口波长约为2.2μm。在本文中，我们展示了一个1950 nm的OCT成像彩绘物体使用超荧光光纤光源在低功率。
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 2.2μm in wavelength. In this paper, we demonstrate a 1950nm OCT for imaging painted objects using a superfluorescent fiber source at low power.
