近年来光谱成像技术在公安、司法鉴定中已经成为了必不可少的基础装备，在文件检验工作中发挥着不可替代的作用。高光谱成像相对于多光谱成像具有更丰富的图像和光谱信息。尝试研究高光谱成像技术在文件检验工作方面的应用，使用V10E－PS 高光谱文检仪简易系统，在可见光波段范围内，实时地采集到光谱分辨率较高、通道数量多，且成像清晰的文字样本数据。用ENVI数据分析软件经过主成分分析、最小噪声分离、主成分分析和独立主成分分析等分析方法后，能够清晰准确的分辨部分数字的修改部位。

In recent years, hyperspectral imaging technology has become essential equipment in public security, judicial identification.It plays an irreplaceable role in document examination.Hyperspectral imaging has richer im-age and spectrum information compared with multispectral imaging.The hyperspectral imaging technology in docu-ment examination application was tried to studied and the V10 E-PS hyperspectral detection instrument of simple system is used.The real-time spectral is higher resolution, channel number, and imaging clear text words this data in the visible wavelength range.The ENVI data analysis software is used including the main component analysis, minimum noise separation, principal component analysis and independent component analysis, it can clearly distin-guish part digital modified position.
