| 摘 要： | 使用共聚焦激光拉曼光谱仪对送检的三份激光打印机墨迹进行鉴定。在高倍显微镜下,发现各检材的细节特征有明显区别;使用785 nm波长激光光源,对各检材进行测定,发现不同检材的激光拉曼光谱图中拉曼峰型,峰个数及峰位移有明显区别。通过上述检测,可以得出鉴定结论。

| Abstract: | This paper is to introduce the experiment of identifying three ink marks from laser printers with confocal Raman spectrometer.Under the high-power microscope,the details of characteristics of the samples are obviously different.The parameters(e.g.type,number,shift) of Raman peaks of the samples,being determined by using 785nm laser light source,are also obviously different.It's easy to obtain the result of appraisal from the determination above. |
