光谱成像法显现浅淡文字

光谱成像法,是近几年法庭科学运用的一重要方法。笔者以热敏字迹、印油文字、无碳复写字迹、针击字迹、纯蓝墨水及蓝黑墨水字迹色料形成的浅淡文字为研究对象,运用光谱成像技术做了系列实验,在普通白光照射下产生光谱影像,与传统可见荧光检验比较效果相当,且检验范围扩大至无荧光效果的色料。实验表明,光谱成像法是显现浅淡文字的一种全新的、有效的检验方法。

On Appearing Weak Character：Spectral Imaging

Recently,spectral imaging has been one of important methods in forensic science.This paper reached the weak character by spectral imaging such as thermosensitive,noncarbon-paper,dot printing,blue-black ink and so on.The technology used to ordinary light.Compared with tradition fluorescent examination,the results was equability,in the same time,the scope of examination had great materials.The paper showed the spectral imaging was one of newly and virtually method.
