摘要在车辆暴力犯罪中，为了掩盖证据，通常会对车辆的受损部位进行人工重新喷漆。检测和恢复重涂汽车涂料中隐藏的子层形态，对于在肇事逃逸案件中提供痕量证据具有重要的价值。光学相干断层扫描（OCT）是一种用于汽车重漆分析的新型法医成像技术，具有无损、非接触、高分辨率和横断面成像等优点。在这项研究中，我们应用了一个定制的光谱域OCT配置，轴向和横向分辨率为~6 μm，以获得人工制备的，内部损坏的，重新涂漆的汽车油漆表面的三维（3D）图像。生成二维（2D）横截面图像以定位受损区域，并进行3D-OCT重建以直接显示重涂涂料表面下的子层。结果表明，3D-OCT技术能够通过体积成像恢复重涂汽车涂料的高分辨率子层图像，从而为法医目的提供更有价值的信息。
Abstract In violent vehicular crimes, the damaged area of a vehicle is usually repainted artificially in order to conceal the evidence. Detecting and recovering the hidden sub-layer morphology of repainted automotive paint is highly valuable for providing trace evidence in hit-and-run cases. Optical coherence tomography (OCT) is a novel forensic imaging technique for repainted automotive paint analysis with the advantages of non-destructive, noncontact, high-resolution and cross-sectional imaging. In this study, we applied a custom-built spectral-domain OCT configuration with ~6 μm axial and lateral resolution to obtain three-dimensional (3D) images of an artificially prepared, internally-damaged, repainted automotive paint surface. Two-dimensional (2D) cross-sectional images were produced to locate the damaged area and 3D-OCT reconstruction was performed to directly visualize the sub-layers beneath the repainted paint surface. The results demonstrate that 3D-OCT technology manages to recover high-resolution sub-layer images of the repainted automotive paint through volumetric imaging, and thus provides more valuable information for forensic purposes.
