摘要
目的探索真空镀膜手印显现技术,提高现场潜在手印显现率。方法通过真空镀膜与"502"熏显法显现常见非渗透性客体上汗潜手印的对比实验,比较二者显现效果优劣。结果真空镀膜法对于显现常见非渗透性客体上的新鲜和陈旧汗潜手印都有着明显的优势。结论真空镀膜是一种更为灵敏的非渗透性客体手印显现方法,是现有手印显现方法的重要补充。
Three hundred and twenty pairs of latent fingerprints on paper were developed using vacuum metal deposition and cyanoacrylate fuming respectively.The results showed that vacuum metal deposition method was more effective for development of new and old sweat fingerprints on no-porous surfaces.
