拉曼光谱阵列面扫描判断蓝色签字笔与印泥的时序研究

朱文时序的检验一直是公安司法鉴定的难点之一, 是文件检验工作者致力研究的难题之一。传统的检验方法灵敏度较低, 特别是对于蓝色签字笔与印文的先后顺序判断很难得到好的效果。为此, 寻求更为简单无损的方法成为了物证检验人员致力追求的目标。将拉曼光谱阵列面扫描成像技术拓展应用于蓝色签字笔与印泥印文先后顺序的研究中, 可以真正意义上实现对检材的无损检验和对检验结果的直观表述, 一方面可以深入研究拉曼光谱阵列面扫描成像技术的各项实验条件及方法特性, 拓展拉曼光谱技术在物证鉴定领域的应用范围; 另一方面也为朱文时序的判断研究提供一种新方法, 使实验结果更加准确可靠。

Research on Determination of Written Order of Blue pen and Inkpad by Raman Streamline Spectroscopy

The determination of written order of writing words and inkpad is a difficulty for the forensic science workers.The sensitivity of conventional examining methods is low,especially for the determination of written order of writing words and inkpad.Looking for other simpler method has become to the goal of the forensic science workers.Applications of raman spectroscopy in the determination of written order of writing words and inkpad have visual and imaginable results.The use of raman streamline spectroscopy on written order of blue pen and inkpad,has not only made up for the shortcomings of traditional test methods,but also expanded the scope of the Applications of Raman spectroscopy at the same time.
