| 摘 要： | 利用傅立叶红外分光成像（FTIR）在保留痕迹证据的同时，又能呈现详细的未处理潜指纹。潜指纹在感光底片上冲洗出来，使用数据处理法从背景材料提取潜指纹的脊模版，包括红外分光谱带强度测量、主要成分分析（（PCA）、次谱带强度计算及这几种方法的综合运用。指纹的痕迹证据还可被恢复和鉴定。

| Abstract: | The capability of Fourier transform infrared(FTIR) spectroscopic imaging to provide detailed images of unprocessed latent fingerprints while also preserving important trace evidence is demonstrated.Unprocessed fingerprints were developed on various porous and nonporous substrates.Data-processing methods used to extract the latent fingerprint ridge pattern from the background material included basic infrared spectroscopic band intensities,addition and subtraction of band intensity measurements,principal comp... |
