| Abstract: | 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. |
