红外显微镜系统在打印字迹鉴别中应用

摘要

Contract documents andsigned documentsetc.are legally protected documents,its authenticity has become an important research in the field of court science.Due to the difference in the composition and content of the toner,the infrared spectrum contains significant differences when the material is different,so the infrared spectrum of counterfeit contracts and other material evidence can play an important role in the identification.Herewe test the infrared spectroscopy of the different print toner by AIM-9000 infrared microscope which has installed the ATR attachment.%合同文本、署名文件等属于受法律保护的文件,其真伪鉴别已成为法庭科学领域的重要研究内容.由于打印墨粉的成分及含量差异,其红外光谱中含有明显的差异性吸收,因此红外光谱对于伪造合同等物证可以起到明显的鉴别作用.本文使用AIM-9000红外显微镜配合ATR附件技术对不同打印机字体进行红外光谱的无损检测,并得到了差异性的测试结果.
