太赫兹脉冲成像（TPI）和光学相干断层扫描（OCT）是两种功能强大的技术，可用于非破坏性地从散射介质中获取高质量的三维图像。在本文中，我们报告的实验结果，使用TPI和红外OCT表征汽车油漆。我们发现，所有四层真实车漆样品的单层厚度都可以通过TPI测量确定，而OCT测量只能对车漆的顶部两层进行成像，尽管图像分辨率更好。OCT能够揭示额外的信息，例如汽车油漆底涂层中金属薄片的形状和方向。
Terahertz pulsed imaging (TPI) and Optical Coherence Tomography (OCT) are two powerful techniques that can be used to non-destructively acquire high quality three-dimensional images from within scattering media. In this paper, we report experimental results of using TPI and infrared OCT for characterizing automobile car paints. We found that the individual layer thickness of all four layers of real-world car paint samples could be determined from TPI measurements whilst OCT measurements can only image the top two layers of the car paints albeit with a better image resolution. OCT is able to reveal additional information such as the shape and orientation of metallic flakes in the base coat of the car paints.
