A finger vein image collection system based on auto-dimming function

GUAN Feng Xu,WANG Ke Jun (College of Automation,Harbin Engineering University,Harbin 150001,China)  
Because each figure has different thickness,the sensor will get different quality of fingers vein images through the fixed infrared intensity light.That means the exposure of these images will be too strong or too dark.In order to get consistency quality finger vein images,auto-dimming circuit is designed which can automatically adjust intensity of the crossing infrared light and keep it relatively stable.At the same time,a finger vein image collection system is designed based on USB2.0 and CMOS. Experimental results show that the finger vein image collected by this system can be clear and stable quality.
