基于真空镀膜技术的疑难客体汗潜手印显现效果因素研究
Research on the factors influencing the appearance effect of difficult object sweat hidden fingerprints based on vacuum coating technology
摘要
Abstract
To investigate the effects of factors such as the placement position,the amount of gold plating,and soaking time on the performance of vacuum coating technology for difficult objects,a series of de-tailed experiments were conducted.The Ruiying VMD900 Latent Fingermark Developer was used to deeply analyze the influence extent of each factor through the control variable method.Meanwhile,com-parative experiments were conducted with Surface Plasmon Resonance technology and oil red O technolo-gy.The results show that for the vertical placement of the object,the fingerprint display effect within a range of 3.8~15.0 cm from the chamber door to the bottom is clear and continuous.Secondly,the a-mount of gold plating has a significant impact on the appearance of fingerprints.When the handprint is relatively new,the optimal gold wire length is 3~4 mm.For waterlogged or aged fingerprints,gold wire length should not exceed 2 mm and uniform gold plating must be ensured.The vacuum coating technology reveals better hand prints on various difficult objects than the other two technologies.关键词
