【摘要】：印章的鉴定是法庭科学的重要组成部分,为了更好的打击刑事犯罪,文章提出了采用傅里叶变换红外图像系统对骑缝章的形成进行了快速无损鉴别研究。结合面扫描和反射模式,先对骑缝章不同部位进行可见图像和红外图像扫描,然后根据印油的红外谱图中吸收峰位置或其特征吸收峰的吸光度比值来鉴定骑缝章是否为一次性形成。红外谱图的结果表明,如果是一次性形成的骑缝章,印油红外谱图中吸收峰位置或其特征吸收峰的吸光度比值基本相近;如果非一次性形成的骑缝章,印油红外谱图中吸收峰位置或其特征吸收峰的吸光度比值相差很大。该法具有快速、准确、客观和不损坏样品等特点。
[Abstract]:Seal identification is an important part of court science. In order to better combat criminal crimes, this paper proposes to use Fourier transform infrared image system to study the formation of seam seal quickly and nondestructive. Combined with surface scanning and reflection mode, the visible images and infrared images of different parts of the seal are scanned, and then the position of the absorption peak in the infrared spectrum of the printed oil or the absorbance ratio of its characteristic absorption peak are identified to determine whether the seal is formed at one time. The results of infrared spectrum show that the absorbance ratio of the absorption peak position or its characteristic absorption peak in the printing oil infrared spectrum is basically similar if it is a one-time riding seal, and the absorbance ratio of the absorption peak position or its characteristic absorption peak in the printing oil infrared spectrum is very different if it is not formed at one time. The method is rapid, accurate, objective and undamaged.
