谈傅立叶红外图像系统法鉴别红色印油的种类

he Identification of Red Stamp Ink Types by Fourier-Transform IR Image System

随着经济的发展,各种合同、证书的使用日益增多,对印油的鉴定愈显重要。关于印油的检验已有一些研究成果,但大都属于有损检验。找到一种简便快捷无损鉴定印油的方法,是很有必要的。采用Spotlight傅立叶变换红外图像系统的反射模式对14种不同品牌的红色印油所形成的印文样品进行直接测试,取得了满意结果,达到了区分不同产地、厂家的目的。该法快速、准确、客观并且不破坏样品。

With the development of economic,all kinds of contracts and certificates are increasingly used,whichl eads the importance of stamp pad ink identification.So far there have been some tests on stamp pad ink,but mosta re destructive tests.So it is very necessary to find a simple and rapid and nondestructive identification of stamp padi nk.Here we have used reflection mode of Fourier-transform IR image system,the stamp mark formed by the 14 typesd ifferentbrand ofred stamp pad ink were tested.Satisfactoryresults havebeen obtained and the purpose of distinguishing in different manufacturers and places of production has been achieved.This method was rapid,accurate,impersonal and nondestructive.
