摘    要:采用傅里叶变换红外显微化学图像系统并结合面扫描和反射模式对书写与盖章的先后顺序进行了无损、快速鉴定,结果表明先盖章后写字的红外谱图中墨水的特征峰吸收明显,先写字后盖章的红外谱图中印油的特征峰吸收明显.该法具有快速、准确、客观和不损坏样品等特点.

关 键 词:傅里叶变换红外显微化学图像系统  面扫描  反射模式  特征峰

Abstract:Using Fourier-transform IR microscopic chemical image system, combined with surface scan and reflection mode, noninvasive fast identification of the sequencing of writing and sealing was carried out. Results indicate that sealing prior to writing leads to evident characteristic peaks of the ink in the IR spectra, while writing prior to sealing results in clear characteristic peaks of the stamp-pad ink in the IR spectra. The method features speediness, exactness, impersonality, and non-invasion to the sam- ple.
Keywords:Fourier-transform IR microscopic chemical image system  Surface scan  Reflection mode  Characteristic peaks
