摘　　要：使用多个波段激发光源,通过实验比较光谱成像技术与传统可见发光照相技术消除印油指印背景的效果.结果表明,使用光谱成像检验技术处理后,达到检验鉴定要求的印油指印数量占所有样本数量的81.3%,而使用传统可见发光照相对相同样本进行处理的效果均不理想.应用光谱成像技术可有效消除印油捺印指印下签字笔字迹背景,其检验效果明显优于其他传统检验技术方法.Various excitation light sources were used to compare the effects of eliminating characters background from ink-fingerprints by spectral imaging and luminescence. Totally 81.3% of ink-fingerprints treated by spectral imaging reached identification level, while they were treated by luminescence, the identification effect is very poor. Spectral imaging shows much more advantages than luminescence in eliminating characters background from ink-fingerprints. As a latest non-destructive optics technique, spectral imaging will show a great potential in fingerprint detection.
