目前现场的指纹的提取一般是通过刷粉、熏显等处理后可对原先无法实时观察的痕迹进行直接照相,并根据需要回去或现场实时分析处理。文章提供的一种高分辨便携式紫红外痕迹数码照相机技术生产方法及系统组成是在专业单反数码照相机基础上,在数码相机感光体表面采用纳米生长技术生成光致发光材料纳米增感层,实现等同专业单反数码照相机分辨率灰度等级的紫外数码成像、数码照片存贮及转存功能的系统。该系统体积小,与普通数码照相机体积大小相似,可实现全光谱照相;无需进行任何的刷粉、熏显等处理即可实时观察、搜索、拍摄,实时存储、图像处理、转存,特别是能实现纸张指纹、曲面指纹等痕迹的快速取证记录。该结构及功能的设备系统是目前紫红外照相功能最强、最便携的单兵痕迹取证记录设备。 At present, fingerprints on the spot are usually taken directly by brushing, smudging and other treatments, and can be directly photographed for the traces that can not be observed in real time and returned or analyzed on the spot as needed. The article provides a high-resolution portable purple infrared trace digital camera technology production method and system composition is based on the professional SLR digital camera on the surface of the digital camera photoconductor using nano-growth technology to generate photoluminescent material nano-sensitized layer to achieve the same Professional SLR digital camera resolution grayscale UV digital imaging, digital photo storage and transfer functions of the system. The system is small in size and similar in size to an ordinary digital camera for full-spectrum photography; real-time viewing, searching, shooting, real-time storage, image processing, dodging, and more, without the need for any brushing, Can achieve paper fingerprints, surface fingerprints and other traces of rapid forensic records. The structure and function of the device system is currently the most powerful infrared photography, the most portable veteran traces forensic recording equipment.
