摘要
无论是紫外反射照相还是紫外光谱成像,其对案发现场的痕迹、物品等物证类检材进行快速成像、无损提取都具有重要的作用。我国应用于物证检验领域的紫外光成像技术的研究,最早涉及的是紫外照相技术,始于上世纪80年代中期,经过几年的探索,取得了世界领先优势。其后,随着全波段CCD照相系统的问世,紫外照相被逐渐推向新的高潮。再后,为了突破全波段CCD照相系统的局限,一些研究者转向探索紫外光谱成像技术在物证检验领域中的应用问题。2009年至今,紫外光谱成像技术应用于物证检验领域的研究涉及痕迹检验、文件检验等多方面,并取得了一批成果。未来相关研究还有很大拓展空间。
Both ultraviolet reflection photography and ultraviolet spectrum imaging play an important role in the rapid imaging and non-destructive extraction of traces,items and other material evidence at the crime scene.The re-search on ultraviolet imaging technology applied in the field of physical evidence inspection in China was first related to ultraviolet photography technology,which began in the mid-1980s.After several years of exploration,it has achieved a leading advantage in the world.With the advent of the full band CCD photography system,ultraviolet photography has gradually been pushed to a new climax.Some researchers turned to the application of ultraviolet spectral imaging tech-nology in the field of material evidence inspection later in order to break through the limitations of full band CCD pho-tography systems.Since 2009,the exploration has involved many aspects such as trace inspection and document inspec-tion,and a number of achievements have been achieved.There is still much room for further research.
