利用文检仪快速鉴别静电复印纸

Fast Identification of Copy Paper with Video Spectral Comparator

在司法鉴定中经常会遇到纸张物证的检验,因此建立一种简便、灵敏、准确的纸张物证鉴别方法十分必要。采用文检仪对20种静电复印纸的荧光特性进行了研究,根据不同激发光照射下样品的荧光颜色和强弱不同,可对样品进行种类鉴别。实验结果表明:该方法具有简单、快速、直观、高效等特点,为纸张物证的检验提供了一种新的技术。

The inspection of the paper evidence is often called upon in forensic science, so it is necessary to establish a simple, sensitive, accurate identification method of paper evidence. The fluorescence properties of 20 different copy papers were investigated by a Video Spectral Comparator （VSC）, and these copy paper can be classified according to the fluorescent colors and intensity. This method is simple, rapid, ocular and highly sensitive, and can be provided to identifying paper evidence for forensic science.
