摘要

介绍了表面等离子体共振成像（SPRI）的原理

应用自行搭建的SPRI系统采集指纹图像

并分析其中的化学物残留。在实验中

测量了粘有Ti O2颗粒的指纹和正常状态下的指纹的SPR吸收光谱

并进行比较分析。实验结果表明:指纹图像有较高的分辨率和对比度;通过对指纹图像进行SPR分析

获得其SPR图谱

能显著观察到其共振波长的变化

从而能实现对残留化学品的检测。

Abstract

The principles of surface plasmon resonance imaging（ SPRI） are introduced

and a home-made SPRI system is utilized to acquire image of fingerprint and analyze chemical residual in fingerprint. In this study

a fingerprint containing Ti O2 residual and a fingerprint in normal state are measured for comparison. Experimental results demonstrate that this SPRI technology improves resolution and contrast of the fingerprint image; by SPR analysis on fingerprint image

obtain its SPR spectrum

wavelength change can be observed obviously

so as to realize chemical residual detecting.
