摘要
探究仿生熏显器显现光滑塑料客体上汗潜指印的可行性。收集常见光滑塑料客体,如手机膜、光盘、以及硬塑料膜等承痕客体,固定仿生熏显器水蒸气的熏显角度为60°,保持喷射水蒸气的温度为60℃,熏显距离为5 cm,熏显时间为4 s。在上述实验条件下,利用仿生熏显器对手机膜、光盘、硬塑料膜进行熏显,在水蒸气消散过后提取汗潜指印。结果表明,仿生熏显器能够有效提取光滑塑料客体上的汗潜指印,指印与塑料客体形成鲜明对比。
Explore the feasibility of the bionic fumigation display instrument showing the sweat latent finger ink on the smooth plastic object.Collect common smooth plastic objects,such as mobile phone film,CD,and hard plastic film and other bearing objects,fix the fumigation Angle of water vapor is 60,keep the temperature of spraying water vapor is 60℃,the fumigation distance is 5 cm,and the fumigation time is 4s.Under the above experimental conditions,the sweat latent fingerprints were extracted on the mobile phone film,CD and hard plastic film by using the bionic fumigation and display instrument.The results show that the bionic display can effectively extract the fingerprints on the smooth plastic object,which forms sharp contrast with the plastic object.
