摘要
目的:运用紫外光谱成像技术检验瓷砖表面护肤品指印,利用指印的紫外光谱影像集及紫外光谱曲线图分析其对紫外线反射及吸收性质,为潜在指纹提取提供技术支持。方法:运用紫外光谱成像技术显现防晒类护肤品指印,分析实验结果,总结实验数据,获得最佳提取波段。结果:紫外光谱成像技术是瓷砖表面防晒类护肤品指印提取和检验的有效手段。结论:紫外光谱成像技术能够显现防晒类护肤品指印,但其显现效果受指印载体的材质、颜色、表面性质及护肤品的成分的影响。
The sunscreen fingerprints on tile surface were developed by UV spectral imaging. The results showed that UV spectral imaging was an effective measure of detecting sunsereen fingerprints. And developing effects depended on various factors, such as material quality, color, surface properties and components.
