弗吉尼亚州阿灵顿的ALM公司最近建立了第一台商用激光指纹检测系统。这种技术主要靠氩激光感应的荧光来显示,它能识别其它方法难以识别的指纹。联邦调查局和少数警察局使用激光识别指纹。 ALM, Arlington, VA, recently built the first commercial laser fingerprint inspection system. This technology is mainly based on argon laser-induced fluorescence, which identifies fingerprints that are hard to identify by other methods. The FBI and a few police stations use laser-based fingerprinting.
