摘要
指纹检测是刑事科学技术中的重要组成部分,对案件侦破起着关键的作用。但是在犯罪现场存在的潜在指纹,可见光方法难以看清和照相固定,必须使用特殊的光学检测技术以有效地显现和提取。主要从以下四个方面讨论了目前光学指纹检测的技术现状和不足:(1)几种提取潜在指纹的主流光学检测方法以及相应特点;(2)不同光学检测方法对应的发光原理;(3)不同光源系统的特点和对探测效果产生的影响;(4)针对一些特殊客体及情况开展的一系列优化指纹所得图样的对策。最后,对现今的一些指纹光学检测技术在疑难客体、自动化和指纹遗留时间方面的不足进行了分析并对未来的发展前景进行了展望。
As a vital part of the criminal science and technology, fingerprint extraction plays a key role in solving criminal cases. Some fingerprints hidden in the scenes of the crimes are hard to be detected and captured by common ways but can be revealed and extracted by specific optical detection effectively. The development status and disadvantages of current optical detection in revealing hidden fingerprints are introduced from the following four aspects. （1） The main optical methods in revealing hidden fingerprints and their corresponding characteristics. （2）The light emitting principals of different optical methods. （3） The features of different light source systems and their influence to the results. （4） A series of measurement to optimize the pictures of fingerprints under some specific backgrounds and situations. In the end, the shortages of current technologies are analyzed and the future development prospects are expected.
