纤维物证检验的研究进展

Research Progress of Examination of Material Evidence of Fiber

纤维是案件现场中最为常见的物证之一。目前,法庭科学领域对纤维物证的发现、提取以及检验方法等都取得了很大的进展。常用的方法有显微镜法、光谱法、色谱法、热分析法等。红外光谱成像技术、太赫兹时域光谱技术、核磁共振法、稳定同位素比质谱法等技术已经应用到实际检验中,并取得了较好的实验结果。

Fiber is one of the common material evidences found on crime scene.At present,great achievements have been made in identifying,extracting and testing fiber evidence in forensic science field.The common methods include microscopic method,spectroscopy,chromatography,thermal analysis and so on.Infrared spectroscopy imaging technology,terahertz time-domain spectroscopy,nuclear magnetic resonance method,and stable isotope ratio mass spectrometry have been applied in practical tests,and remarkable results have been obtained.
