摘要
采用显微拉曼光谱和电阻测量技术,选择30支不同品牌和型号的黑色签字笔书写的墨迹样本,在分析所采集的拉曼谱图和电阻数据的基础上,对墨水的成分属性进行综合鉴别。结果表明,两种技术方法之间具有互证性和互补性,可以为黑色签字笔的种属鉴别提供一种准确、无损、便捷的新思路,适用于法庭科学添改文件鉴别,增强物证的证据效力。
Abstract
Applying Raman spectroscopy and electric resistance measurement technology to identify the ingredients and properties of 30 black gel pen ink sample of different brands and models,based on the collected data of Raman spectroscopy and electric resistance measurement technology.The results show that these two measurements are complementary and mutual proved,providing an accurate and handy method of black gel pen identification.It can be used to distinguish the questioned documents in forensic science,enhancing the validity of evidence.
