摘　　要：介绍了一种新型线阵直擦式指纹传感器芯片AES2510的结构特点、性能及其工作原理,设计并实现了基于AES2510和处理器芯片TMS320VC5416的指纹图像采集系统。该系统具有自动指纹检测、功耗低、成本低、体积小、寿命长、自适应能力强等特点。采用不同的参数进行了系统实验,结果表明:该系统采集的指纹图像具有纹理清晰、噪声低、图像有效面积大等优点,可以满足指纹识别系统的需要。The characteristics of a new swipe authentec fingerprint sensor AES2510, as well as its operating principles, structure features are given. Design and implementation of a fingerprint capture system, which is based on the new swipe sensor AES2510 and a high performance DSP（TMS320VC5416） ,are introduced. The system has automatically detecting finger,low power,less price,smaller size,long life and better adaptability. It is tested by different parameters. The experimental results show that the image textures by the system are clearer, the background noise is smaller and effective area of a image is larger. So the system can satisfy the requirements of the fingerprint identification systems.
