碘热升华喷枪显现潜手印的应用研究

Development of latent finger print by using the iodine heat-sublimating spray-gun

本文提出一种以石英灯为加热器的碘热升华喷枪显现潜手印的新方法。实验表明,该技术方法操作简便,适用范围广,手印显出率高,尤其是显现遗留在墙面、本色铝合金表面、UPVC表面的潜手印效果明显。

This article introduce a new method to make the latent fingerprints emerge by using the iodine heat-sublimating spray-gun heated by a sort of quartz lamp. Experiments indicate that this method can be widely applied and can show fingerprints in a effective way, especially in showing the latent fingerprints left on the wall surface, on the aluminum alloy surface, and on UPVC surface.
