摘要
本文在查阅相关专利的基础上,模拟了二次成像非共轴光学采集系统,该系统可校正与光轴成倾斜物面所引起的畸变,可使仪器体积小,重量轻,成本低,便于批量生产。经过优化后,可使指纹采集系统的畸变控制在0.2%以内,满足指纹识别的要求。
On the basis of the relevant patent, this paper simulates the secondary imaging optical system which is non coaxial. The system can correct the distortion caused by optical axis tilted surface. Furthermore, the system can make the instrument smaller in size, lighter in weight, lower in cost and convenient for mass production. After optimization, the distortion of the fingerprint acquisition optical system is less than 0.2%, meeting the requirements of fingerprint identification.
