| 摘 要： | 目的建立一种无损、灵敏、直观的同种同色涂抹掩盖字迹的显现方法。方法依据涂抹掩盖字迹油墨物质的同色异谱特征,利用可见光滤波型多光谱成像检验系统进行检验。结果黑色圆珠笔、蓝色圆珠笔、黑色签字笔和蓝色签字笔相互涂抹掩盖形成的同种同色涂抹掩盖样本,利用可见光滤波型多光谱成像检验系统进行检验,显效率分别为90.5%、69.1%、49.5%、78.6%,显现效果良好。结论多光谱成像技术可以显现同种同色涂抹掩盖字迹,且具有良好的显现效果。 |

| Abstract: | Objective To establish a non-destructive method for visualizing the handwriting covered by same color inks.Method The covered handwritings were examined by using spectral imaging technology.Results For ball pen and gel pen,black and blue handwritings covered with the same color inks have been visualized by spectral imaging.Conclusion Spectral imaging technology can be used for visualizing the handwriting covered by same color inks. |
| Keywords: | spectral imaging covered handwriting metamerism characteristics |
