摘要: 該文針對虹膜識別系統(tǒng)中虹膜采集裝置采集虹膜圖像很不靈活的問題，給出一種利用加波陣面來延長景深的方法。文中詳細分析了其可行性及設(shè)計方法，并給出了運用此系統(tǒng)采集虹膜，進行虹膜識別的比較實驗結(jié)果。該方法對虹膜識別的推廣具有很高的參考價值。

Abstract: The procedure of captured iris requires considerable cooperation from the user. The method using wavefront to extend the depth-of-field of the image capture system is expatiated in the paper. The feasibility and method of realization are given in detail. Finally, the result of iris recognition contrast experimentation using this system is introduced. The method has high value for popularizing iris recognition. -
