| Abstract: | Criminal investigation is a application area. It needs all science ＆ technology display their prowess. And the laser application is becoming popular in Criminal investigation. Trail emergence is the key tache of the Trail emergence. And the article introduces optics theory of Trail emergence. Designing based on 532nm diode pumped laser as single color trail search source （single color source for short）. Prove through the practical application, compare to traditional muhiband source this source had improved much in footprint search ＆ fingerprint emergence. Meanwhile, this source can search footprint, hair and fibre in large fiat scope, so it has great practical value. |
