摘要
介绍当前基于光学、电容、超声波、无接触采集等新兴技术的活体指纹采集仪工作原理和应用现状,以及对实务工作的影响。基于TFT工艺的技术进步,使得活体指纹采集仪的体积可大大缩小、轻薄便携,并可通过智能手机等实现移动警务应用。展望了活体指纹采集仪的未来发展趋势。
The working principle and application status of living fingerprint acquisition instrument,as well as its influence on practical work,is introduced based on optical,capacitive,ultrasonic,contactless acquisition and other emerging technologies.Based on the technical progress of TFT process,the volume of living fingerprint acquisition instrument can be greatly reduced,thin and portable,and can be realized through smart phones and other mobile police applications.The future development trend of living fingerprint collection instrument is also prospected.
