采用蓝、绿双色激光对遗留在不同客体上被覆盖的指纹进行显现,与传统的刑事勘查光源相比,激光具备光纯度高、功率高、穿透力强和相干性好等特性,使得激光在显现被覆盖指纹方面取得了一定的效果。激光显现技术将在显现疑难指纹领域具备广泛和有价值的应用前景。 Compared with the traditional criminal exploration light source, the laser has the characteristics of high optical purity, high power, strong penetrating power and good coherence, so that the blue and green two-color laser can reveal the fingerprints that are left over on different objects, In the show was covered fingerprint has achieved some results. Laser display technology will have a broad and valuable application prospect in the field of developing difficult fingerprints.
